Make all gcc.dg/guality/const-volatile.c subtests PASS under LTO.

Some subtests were reported as UNSUPPORTED when running under LTO.
That was just because the relevant variables were optimized out.
Mark those variables as used. Now const-volatile reports 192 PASS.

gcc-gdb-test.exp: Handle old GDB "short int" and "long int" types.

Old GDB might show short and long as short int and long int. This made
gcc.dg/guality/const-volatile.c ans restrict.c fail on older GDBs.
According to the patch that changed this in newer versions of GDB
this was a bug: https://sourceware.org/ml/gdb-patches/2012-09/msg00455.html

The patch transforms the types "short int" and "long int" coming from
GDB to plain "short" and "long". And a variant has been added to the
const-volatile.c testcase to make sure short and long long are handled
correctly now with older GDB.

gcc/testsuite/ChangeLog

* lib/gcc-gdb-test.exp (gdb-test): Transform gdb types "short int"
and "long int" to plain "short" and "long".
* gcc.dg/guality/const-volatile.c (struct bar): New struct
containing short and long long fields.

Remove LIBGCC2_LONG_DOUBLE_TYPE_SIZE target macro.

This patch removes the target macro LIBGCC2_LONG_DOUBLE_TYPE_SIZE.

After recent changes, this macro was used in two ways in libgcc: to
determine the mode of long double in dfp-bit.h, and to determine
whether a particular mode has excess precision for use in complex
multiplication.

The former is concerned specifically with long double: it relates to
use of strtold for converting between decimal and binary floating
point.  This is replaced by comparing __LDBL_MANT_DIG__ with the
appropriate __LIBGCC_*_MANT_DIG__ macro.  The latter is replaced
__LIBGCC_*_EXCESS_PRECISION__ predefined macros.

Remarks:

* Comparing (__LDBL_MANT_DIG__ == __LIBGCC_XF_MANT_DIG__) is more
  fragile than it looks; it's possible for XFmode to have 53-bit
  mantissa (TARGET_96_ROUND_53_LONG_DOUBLE, on FreeBSD and
  DragonFlyBSD 32-bit), in which case such a comparison would not
  distinguish XFmode and DFmode as possible modes for long double.
  Fortunately, no target supporting that form of XFmode also supports
  long double = double (but if some target did, we'd need e.g. an
  additional macro giving the exponent range of each mode).

  Furthermore, this code doesn't actually get used for x86 (or any
  other target with XFmode support), because x86 uses BID not DPD and
  BID has its own conversion code (which handles conversions for both
  XFmode and TFmode without needing to go via strtold).  And FreeBSD
  and DragonFlyBSD aren't among the targets with DFP support.  So
  while in principle this code is fragile and it's a deficiency that
  it can't support both XFmode and TFmode at once (something that
  can't be solved with the string conversion approach without libc
  having TS 18661 functions such as strtof128), all these issues
  should not be a problem in practice.

* If other cases of excess precision are supported in future, the code
  for defining __LIBGCC_*_EXCESS_PRECISION__ may need updating.
  Although the most likely such cases might not actually involve
  excess precision for any mode used in libgcc - FLT_EVAL_METHOD being
  32 to do _Float16 arithmetic on _Float32 should have the effect of
  _Complex _Float16 arithmetic using __mulsc3 and __divsc3, rather
  than currently nonexistent __mulhc3 and __divhc3 as in bug 63250 for
  ARM.

* As has been noted in the context of simultaneous support for
  __float128 and __ibm128 on Power, the semantics of macros such as
  LONG_DOUBLE_TYPE_SIZE are problematic because they rely on a
  poorly-defined precision value for floating-point modes (which seems
  to be intended as the number of significant bits in the
  representation, e.g. 80 for XFmode which may be either 12 or 16
  bytes) uniquely identifying a mode (although defining an arbitrarily
  different value for one of the modes you wish to distinguish may
  work as a hack).  It would be cleaner to have a target hook that
  gives a machine mode directly for float, double and long double,
  rather than going via these precision values.  By eliminating all
  use of these macros (FLOAT_TYPE_SIZE, DOUBLE_TYPE_SIZE,
  LONG_DOUBLE_TYPE_SIZE) from code built for the target, this patch
  facilitates such a conversion to a hook (which I suppose would take
  some suitable enum as an argument to identify which of the three
  types to return a mode for).

  (The issue of multiple type support for DFP conversions would apply
  in that Power case.
  <https://gcc.gnu.org/ml/gcc-patches/2014-07/msg01084.html> doesn't
  seem to touch on it, but it would seem reasonable to punt on it
  initially as hard to fix.  There would also be the issue of getting
  functions such as __powikf2, __mulkc3, __divkc3 defined, but that's
  rather easier to address.)

runtime: Mark runtime_goexit function as noinline.

If the compiler inlines this function into kickoff, it may reuse
the TLS block address to load g. However, this is not necessarily
correct, as the call to g->entry in kickoff may cause the TLS
address to change. If the wrong value is loaded for g->status in
runtime_goexit, it may cause a runtime panic.

By marking the function as noinline we prevent the compiler from
reusing the TLS address.
