Remove redundant option -menable-unsafe-fp-math.
There are currently two options that are used to tell the compiler to perform
unsafe floating-point optimizations:
'-ffast-math' and '-funsafe-math-optimizations'.
'-ffast-math' is enabled by default. It automatically enables the driver option
'-menable-unsafe-fp-math'.
Below is a table illustrating the special operations enabled automatically by
'-ffast-math', '-funsafe-math-optimizations' and '-menable-unsafe-fp-math'
respectively.
Special Operations -ffast-math -funsafe-math-optimizations -menable-unsafe-fp-math
MathErrno 0 1 1
FiniteMathOnly 1 0 0
AllowFPReassoc 1 1 1
NoSignedZero 1 1 1
AllowRecip 1 1 1
ApproxFunc 1 1 1
RoundingMath 0 0 0
UnsafeFPMath 1 0 1
FPContract fast on on
'-ffast-math' enables '-fno-math-errno', '-ffinite-math-only',
'-funsafe-math-optimzations' and sets 'FpContract' to 'fast'. The driver option
'-menable-unsafe-fp-math' enables the same special options than
'-funsafe-math-optimizations'. This is redundant.
We propose to remove the driver option '-menable-unsafe-fp-math' and use
instead, the setting of the special operations to set the function attribute
'unsafe-fp-math'. This attribute will be enabled only if those special
operations are enabled and if 'FPContract' is either 'fast' or set to the
default value.

Allow #pragma float_control(push|pop) within a language linkage specification
Currently, we prohibit this pragma from appearing within a language
linkage specification, but this is useful functionality that is
supported by MSVC (which is where we inherited this feature from).
This patch allows you to use the pragma within an extern "C" {} (etc)
block.

[clang][cli] Remove -f[no-]trapping-math from -cc1 command line
This patch removes the -f[no-]trapping-math flags from the -cc1 command line. These flags are ignored in the command line parser and their semantics is fully handled by -ffp-exception-mode.
This patch does not remove -f[no-]trapping-math from the driver command line. The driver flags are being used and do affect compilation.
