Darwin, objective-c - register gnu-runtime headers correctly.

Darwin is able to use two runtimes for objective-c; the
default is its native "NeXT" runtime, but also it can build
code using the "gnu-runtime".  In order to do this, we have to
be able to find the gnu-runtime headers (which are installed
into the compiler's tree).

The process to do this is erroneously prepending the sysroot
to this when a sysroot is in force.  The gnu-runtime headers have
never been installed in a Darwin (macOS) SDK so we must make
sure that they are found local to the compiler.

rs6000: Some rs6000_emit_epilogue improvements

This uses epilogue_type directly.  It also changes some ints to bools,
declares variables later, and simplifies some code.

There is one actual change:

   else if (info->push_p
           && DEFAULT_ABI != ABI_V4
-          && !crtl->calls_eh_return)
+          && epilogue_type != EPILOGUE_TYPE_EH_RETURN)
     {
       /* Prevent reordering memory accesses against stack pointer restore.  */

(different because calls_eh_return can be true for sibcalls).  This is
a bugfix.  The code was never exercised.

One place in the epilogue still uses crtl->calls_eh_return.  If that
is changed the prologue has to have a corresponding change, and the
emit_prologue function does not have an epilogue_type parameter, so
bail on changing this for now.  We might want to do this (saving the
CR fields to separate stack slots) always, not just for functions
calling eh_return, but that will require more investigation.

* config/rs6000/rs6000.c (restore_saved_cr): Change a boolean
argument to be type bool (was int before).
(rs6000_emit_epilogue): Simplify some code.  Declare some variables
at first use.  Use type bool for some variables.  Fix a theoretical
eh_return bug for svr4.

rs6000: Add "enabled" attribute

This adds the "enabled" attribute to the rs6000 backend.  It uses the
(new) "isa" attribute to automatically select which instruction
alternatives should be enabled.

For now it allows isa strings of "p5", "p6", "p7", meaning the
instructions introduced on that CPU, not requiring vectors; and "p7v",
"p8v", "p9v" for the same, but with vectors.

These are currently mapped to TARGET_POPCNTB, TARGET_CMPB,
TARGET_POPCNTD, TARGET_VSX, TARGET_P8_VECTOR, and TARGET_P9_VECTOR;
that will change to something a bit saner later.

* config/rs6000/rs6000.md (isa): New attribute.
(enabled): New attribute.

libfortran/90038: Use posix_spawn instead of fork

fork() semantics can be problematic.  Most unix style OS'es have
posix_spawn which can be used to replace fork + exec in many cases.
For more information see
e.g. https://www.microsoft.com/en-us/research/uploads/prod/2019/04/fork-hotos19.pdf

This replaces the one use of fork in libgfortran with posix_spawn.

PR libstdc++/85965 move is_invocable assertions again

This is another attempt to reduce how often the assertions are
evaluated, so that code which doesn't try to use the function objects
doesn't need them to be invocable.

For _Rb_tree we access the _M_key_compare object directly, so can't put
the assertions in an accessor function for it. However, every invocation
of _M_key_compare is accompanied by a use of _S_key, so the assertions
can be put in there.  For _Hashtable there are member functions that are
consistently used to obtain a hash code or test for equality, so the
assertions can go in those members.

compiler: use SHA1-hash for symname for long gcbits symbols

    The current scheme used by the compiler for "gcbits" symbols involves
    generating a symbol name based on a 32-char encoding of the bits data.
    This scheme works well in most cases but can generate very long symbol
    names in rare cases. To help avoid such long symbol names, switch to a
    different encoding scheme based on the SHA1 digest of the payload if
    the symbol size would be too large.

    Fixes golang/go#32083.

    compiler: make value method of direct interface type takes pointer

    Currently, a value method of a direct interface type takes the
    value of the receiver, which is pointer shaped, as the first
    parameter. When this method is called through interface, we
    actually pass the interface data as a pointer. On most platforms
    this is ok, as the underlying calling convention is the same,
    except that on SPARC32, the calling convention is actually
    different.

    This CL changes the method function actually takes a pointer.
    The function will convert the pointer to the pointer-shaped
    receiver type (a no-op conversion from machine code's aspect).
    For a direct call, in the caller we convert the receiver to a
    pointer (also no-op conversion) before invoking the method. For
    an interface call, we pass the pointer as before. This way, it is
    consistent that we always pass a pointer.

    Hopefully this fixes SPARC32 build and https://gcc.gnu.org/PR90482.

compiler: add intrinsics for runtime/internal/sys functions

    runtime/internal/sys.Ctz32/64 and Bswap32/64 are currently
    implemented with compiler builtin functions. But if they are
    called from another package, the compiler does not know and
    therefore cannot turn them into compiler intrinsics. This CL
    makes the compiler recognize these functions and turn them into
    intrinsics directly, as the gc compiler does.

    This CL sets up a way for adding intrinsics in the compiler.
    More intrinsics will be added in later CLs.

    Also move the handling of runtime.getcallerpc/sp to the new way

    This CL improves the escape analysis to track interface
    conversions, and reduces these allocations.

    Implicit interface conversions were mostly added late in the
    compilation pipeline, after the escape analysis. For the escape
    analysis to see them, we move the introduction of these
    conversions earlier, right before the escape analysis.

    Now that the compiler can generate interface conversions inlined,
    gcc/testsuite/go.test/test/nilptr2.go needs to be adjusted as in
    golang.org/cl/176579, so the use function does an actual use.

    Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/176459

* go.test/test/nilptr2.go: Change use function to actually do
something.
