[PR86747] tsubst friend tpl ctxt before looking it up for dupes
When a member template is redeclared as a friend, we enter the context
of the member before looking it up, and then we check that the decls
are compatible. However, when the member template references template
types of the enclosing context, say an enclosing template class, the
compare fails because the friend decl is already tsubsted, whereas the
looked up name isn't.
The problem is that the enclosing context is taken from the friend
declaration before tsubsting it, so we look up in the context of the
generic template instead of that of the tsubsted one we're
specializing. The solution is to tsubst the enclosing context when
it's a non-namespace scope.

[PR86397] resolve nondependent noexcept specs early in C++1[14]
build_noexcept_spec refrained from resolving nondependent noexcept
expressions when they were not part of the function types (C++ 11 and
14). This caused problems during mangling: canonical_eh_spec, when
called on the template function type, would find an unresolved but not
explicitly deferred expression, and nothrow_spec_p would reject it.
We could relax the mangling logic to skip canonical_eh_spec, but since
-Wnoexcept-type warns when mangling function names that change as
noexcept specs become part of types and of mangling in C++17, and the
test at mangling time may give incorrect results if the spec is not
resolved, we might as well keep things simple and resolve nondependent
noexcept specs sooner rather than later. This is what this patch does.

avoid null ptr deref in cselib_record_sets
Jeff Law tells me h8300-elf fails gcc.c-torture/compile/pr49029.c
with -O2 -g -mint32 -mh. This patch fixes it.
The problem is that strict low part handling in cselib_record_sets
assumes src_elt is not NULL. That src_elt is taken from a strict low
part set, but it won't always have a src_elt to begin with. In this
case, it's because src is a volatile MEM; we don't record values for
those.
Although we could fix the problem by testing for a NULL src_elt before
creating the zero extends corresponding to strict low part sets of
formerly const0_rtx REGs, there's no point in recording the additional
set that we won't be able to use anyway.
We could still record that the whole register has a zero-extend of
the value stored in the narrower-mode strict low part of the register,
but is that of any use? I guess not, but if we find otherwise, we can
change that later.

runtime: add precise stack scan support
This CL adds support of precise stack scan using stack maps to
the runtime. The stack maps are generated by the compiler (if
supported). Each safepoint is associated with a (real or dummy)
landing pad, and its "type info" in the exception table is a
pointer to the stack map. When a stack is scanned, the stack map
is found by the stack unwinding code by inspecting the exception
table (LSDA).
For precise stack scan we need to unwind the stack. There are
three cases:
- If a goroutine is scanning its own stack, it can unwind the
stack and scan the frames.
- If a goroutine is scanning another, stopped, goroutine, it
cannot directly unwind the target stack. We handle this by
switching (runtime.gogo) to the target g, letting it unwind
and scan the stack, and switch back.
- If we are scanning a goroutine that is blocked in a syscall,
we send a signal to the target goroutine's thread, and let the
signal handler unwind and scan the stack. Extra care is needed
as this races with enter/exit syscall.
Currently this is only implemented on linux.

testsuite: turn down verbosity of "process-message"
When debugging a failing test, I typically invoke DejaGnu at
verbosity level 2 (via RUNTESTFLAGS="-v -v dg.exp=something"),
so that DejaGnu prints the command line used to invoke the
compiler; specifically these two sites:
target.exp "Invoking the compiler as "
remote.exp "Executing on $hostname"
which are both verbosity level 2.
Unfortunately I run into an O(n^2) issue with logging from
process-message:
verbose "process-message:\n${dg-messages}" 2
where, as each message each processed, it emits the state
of dg-messages, containing the new message and all messages so far,
leading to exponentially-increasing output at level 2 as more test
messages are added.
This patch papers over the problem by moving the
problematic message to verbosity level 3.

[PR85569] skip constexpr target_expr constructor dummy type conversion
The testcase is the work-around testcase for the PR; even that had
started failing. The problem was that, when unqualifying the type of
a TARGET_EXPR, we'd create a variant of the type, then request the
conversion of the TARGET_EXPR_INITIAL to that variant type. Though
the types are different pointer-wise, they're the same_type_p, so the
resulting modified expr compares cp_tree_equal to the original, which
maybe_constant_value flags as an error. There's no reason to
construct an alternate TARGET_EXPR or CONSTRUCTOR just because of an
equivalent type, except for another spot that expected pointer
equality that would no longer be satisfied. Without relaxing the
assert in constexpr_call_hasher::equal, g++.robertl/eb73.C would

cmd/go: allow buildmode c-archive for gccgo on ppc64
In buildmodeinit, the c-archive buildmode is flagged as invalid
on linux/ppc64 for gccgo when it should be valid. This happens
because the check against the gccgo flag is done after the checks
for valid GOOS/GOARCH pairs instead of before as is done for all
other buildmode cases in this switch. This corrects the problem and
allows several of the gccgo gotools testcases to pass on linux/ppc64.

[Ada] Fixes for various wrong and missing error messages on ACATS B85100[567]
GNAT was missing errors as well as issuing messages on legal lines in
new ACATS tests for illegal renamings of discriminant-dependent
components. Cases that are fixed include object names involving
qualified expressions, dereference cases, and generic formal access and
formal derived types. Better implements the "known to be constrained"
rules in the Ada RM.
Tested by new ACATS tests B85100[567] that are soon to be released.

* sem_aux.adb (Object_Type_Has_Constrained_Partial_View): Return
True for an untagged discriminated formal derived type when
referenced within a generic body (augments existing test for
formal private types).
* sem_util.adb (Is_Dependent_Component_Of_Mutable_Type): If the
prefix of the name is a qualified expression, retrieve the
operand of that. Add a test of whether the (possible)
dereference prefix is a variable, and also test whether that
prefix might just be of an access type (occurs in some implicit
dereference cases) rather than being an explicit dereference.
Retrieve the Original_Node of the object name's main prefix and
handle the possibility of that being a qualified expression.
Remove special-case code for explicit dereferences that don't
come from source. Add test for the renaming not being within a
generic body for proper determination of whether a formal access
type is known to be constrained (it is within a generic spec,
but not in the body). Fix an existing incorrect test for
renaming of a discriminant-dependent component of a untagged
generic formal type being within a generic body, adding test of
taggedness and calling In_Generic_Body (now properly checks for
cases where the renaming is in a nongeneric body nested within a
generic). Return False in cases where the selector is not a
component (or discriminant), which can occur for
prefixed-notation calls.
