[C] Avoid exposing internal details in aka types
The current aka diagnostics can sometimes leak internal details that
seem more likely to be distracting than useful. E.g. on aarch64:
void f (va_list *va) { *va = 1; }
gives:
incompatible types when assigning to type ‘va_list’ {aka ‘__va_list’} from type ‘int’
where __va_list isn't something the user is expected to know about.
A similar thing happens for C++ on the arm_neon.h-based:
float x;
int8x8_t y = x;
which gives:
cannot convert ‘float’ to ‘int8x8_t’ {aka ‘__Int8x8_t’} in initialization
This is accurate -- and __Int8x8_t is defined by the AArch64 PCS --
but it's not going to be meaningful to most users.
This patch stops the aka code looking through typedefs if all of
the following are true:
(1) the typedef is built into the compiler or comes from a system header
(2) the target of the typedef is anonymous or has a name in the
implementation namespace
(3) the target type is a tag type or vector type, which have in common that:
(a) we print their type names if they have one
(b) what we print for anonymous types isn't all that useful
("struct <anonymous>" etc. for tag types, pseudo-C "__vector(N) T"
for vector types)
The patch does this by recursively looking for the aka type, like the
C++ frontend already does. This in turn makes "aka" work for distinct type
copies like __Int8x8_t on aarch64, fixing the ??? in aarch64/diag_aka_1.c.

[Darwin, machopic 8/n] Back out part of PR71767 fix.
We applied a conservative, but fairly large, hammer to fix PR71767.
However, ideally, we want minimise the number of symbols visible to
ld64 and to match the cases emitted by clang (since that's what ld64
is expecting). Now we've improved the handling of indirections, we
can make the indirection symbols local when they are in the regular
non-lazy symbol pointers section. We will continue to make any
indirections in the data section visible (since right now we have no
way to track if a given symbol follows a weak global).
This change makes no difference to handling of labels for constants
(to be revised in a future patch).
There's a mechanical change to a number of tests (allowing 'l' or 'L'
as the indirection symbol prefix).

compiler: mangle dots in pkgpath
We need to mangle dots to avoid problems with -fgo-pkgpath=a.0.
That will confuse the name mangling, which assumes that names
entering the mangling cannot contain arbitrary dot characters.
We don't need to mangle other characters; go_encode_id will handle them.

Extend subst to simplify CONST_INT inside SIGN_EXTEND.
This addresses PR 91860 which has four testcases triggering internal errors.
The problem here is that in combine when handling debug insns, we are trying
to substitute
(sign_extend:DI (const_int 8160 [0x1fe0]))
as the value for
(reg:DI 78 [ _9 ])
in the debug insn
(debug_insn 29 28 30 2 (var_location:QI d (subreg:QI (reg:DI 78 [ _9 ]) 0)) "tmp4.c":11:5 -1
(nil))
This eventually triggers an abort because 8160 is not a sign-extended
QImode value.
In subst there is already code check for a CONST_INT inside a ZERO_EXTEND and
simplify it. This needs to be extended to also handle a SIGN_EXTEND the same
way.

Support _Decimal* keywords for C2x.
ISO C2x adds decimal floating point as an optional standard feature.
This patch accordingly makes GCC accept the _Decimal* keywords in
strict C2x mode, using pedwarn_c11 to get a warning for
-Wc11-c2x-compat. (Constants, where the pedwarn is in libcpp, will be
dealt with separately.)
The _Decimal* keywords are marked with D_EXT, meaning they are not
considered keywords at all in strict conformance modes. This is
contrary to the normal practice for most implementation-namespace
keywords, which are accepted in all standards modes but with
appropriate pedwarns for older standards. This patch removes D_EXT
from those keywords so they are accepted as keywords for all
standards, consequently removing the gcc.dg/dfp/keywords-ignored-c99.c
test that is no longer valid.
(A new D_C2X for keywords will still be needed if any new keywords get
added that aren't in the implementation namespace for older standards;
there are proposals for such keywords, albeit as predefined macros
that might not actually need new keywords in the compiler in all
cases. If the DFP keywords end up as decimal32 etc., of course
appropriate compiler and testcase changes will be needed, and a
version of keywords-ignored-c99.c would make sense again with such
spellings.)

Update DFP macros in float.h for C2x and TS 18661-2.
GCC's <float.h> includes various macros for decimal floating-point
types, defined if __STDC_WANT_DEC_FP__, as defined in TS 24732.
TS 18661-2 and C2X make some changes to those macros. In TS 18661-2,
they are to be defined if __STDC_WANT_IEC_60559_DFP_EXT__, and the
*_SUBNORMAL_MIN macros are renamed to *_TRUE_MIN. In C2X, the macros
are to be defined whenever DFP is supported, without needing any
feature test macro to be defined.
This patch updates the header accordingly. There is no existing
predefined macro for whether the target supports DFP; rather than
adding a new macro for that purpose, this patch changes the predefined
macros used in <float.h> so that they are only defined when DFP is
supported and thus can be used as conditionals; this is the same way
predefined macros for _FloatN and _FloatNx types work. Although
formally TR 24732 and TS 18661-2 say nothing about implementations
lacking DFP support, it seems appropriate to avoid defining the macros
in <float.h>, in the absence of DFP support, even if the respective
feature test macros are defined.
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested
the c2x-float-no-dfp-* tests for aarch64-linux-gnu to make sure they
do pass in a no-DFP configuration.
