about argument type mismatch.

This gives a nicer diagnostic in cases like
  printf(fmt,
         i);
where previously the snippet just pointed at 'fmt' (with a note at the
definition of fmt).

It's a wash for cases like
  printf("%f",
         i);
where previously we snippeted the offending portion of the format string,
but didn't indicate which argument was at fault.

used by the preprocessor.  Apple's GCC also supported a -A option for linking.

The ld man page has the following:
 -A basefile - Obsolete incremental load format.  This option is obsolete.

Nick Kledzik confirms this option is no longer needed/supported.

Disambiguate past such a potential problem, and use the absence of 'typename'
to break ties in favor of a parenthesized thingy being an initializer, if
nothing else in the declaration disambiguates it as declaring a function.

TableGen already computes register units as the basic unit of
interference. We can use that to compute the set of overlapping
registers.

This means that we can easily compute overlap sets for one register at a
time. There is no benefit to computing all registers at once.

llc to recognize MIPS16 as a MIPS ASE extension. -mips16 will mean the
mips16 ASE for mips32 by default.

As part of fixing of adding this we discovered some small changes that
need to be made to MipsInstrInfo::storeRegToStackSLot and
MipsInstrInfo::loadRegFromStackSlot. We were using some "==" equality tests
where in fact we should have been using Mips::<regclas>.hasSubClassEQ instead,
per suggestion of Jakob Stoklund Olesen.

When widening an existing <def,reads-undef> operand to a super-register,
it may be necessary to clear the <undef> flag because the wider register
is now read-modify-write through the instruction.

Conversely, it may be necessary to add an <undef> flag when the
coalescer turns a full-register def into a sub-register def, but the
larger register wasn't live before the instruction.

This happens in test/CodeGen/ARM/coalesce-subregs.ll, but the test
is too small for the <undef> flags to affect the generated code.

Also fix the diagnostic messages to properly handle -Wno- options.  Previously,
