For compatibility with xcrun and the behaviour of the clang driver, make use
of the setting of the SDKROOT environment variable when it is available.
This applies to both finding headers and libraries (i.e. it is also passed to
ld64).
Priority:
1. User's command-line specified --sysroot= or -isysroot.
2. The SDKROOT variable when set, and validated.
3. Any sysroot provided by --with-sysroot= configuration parameter.
SDKROOT is checked thus:
1. Presence.
2. That it starts with "/" (i.e. 'absolute').
3. That it is not "/" only (since that's the default).
4. That it is readable by the process executing the driver.
This is pretty much the same rule set as used by the clang driver.
NOTE: (3) might turn out to be overly restrictive in the case that we
have configured with --with-sysroot= and then we want to run on a system
with an installation of the headers/libraries in /. We can revisit this
if that turns out to be an important use-case.
So one can do:
xcrun --sdk macosx /path/to/gcc ....
and that provides the SDK path as the sysroot to GCC as expected.
CAVEAT: An unfortunate effect of the fact that "gcc" (and "g++") are
executables in the Xcode installation, which are found ahead of any such
named in the $PATH:
PATH=/path/to/gcc/install:$PATH
xcrun --sdk macosx gcc ....
does *not* work, instead that executes the clang from the xcode/commmand
line tools installation.
PATH=/path/to/gcc/install:$PATH
xcrun --sdk macosx x64_64-apple-darwinXX-gcc ...
does work as expected, however.

As part of the integration of TS 18661-1 into C2x, many features
became unconditional features not depending on any feature test macro
being defined. This patch updates the conditionals on the *_WIDTH
macros in limits.h and stdint.h accordingly so that they are defined
for C2x. The macro CR_DECIMAL_DIG in float.h does still require
__STDC_WANT_IEC_60559_BFP_EXT__ to be defined, and a test for this is
added.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

My change to the -fipa-ra bookkeeping used ALL_REGS as the supposedly
safe default assumption, but ALL_REGS isn't literally all registers,
just a close approximation.
This caused a bootstrap failure on arm-linux-gnu, where the condition
code register isn't in ALL_REGS and so was being masked out of some
call-clobbered sets.

Jeff pointed out that gcc.target/mips/call-clobbered-4.c started
failing after the function-abi series. This is because IRA used
to treat partly call-clobbered registers as hard conflicts and
so wouldn't consider them for -fcaller-saves. Now that we treat
call clobbers the same way regardless of where they come from,
we can use $f21 as a caller-save register. This in turn means
that -Os is no longer a special case in call-clobbered-3.c.
(The new code is the same size as the old code.)
