Toma Tabacu 94ea6867cc [mips] Don't propagate -mfpxx by default if soft/single float were also set.
Summary:
If the driver is only given -msoft-float/-mfloat-abi=soft or -msingle-float,
we should refrain from propagating -mfpxx, unless it was explicitly given on the
command line.

Petar Jovanovic 1dbc317736 [Mips] Generate warning for invalid '-mnan' and '-march' combinations
This patch generates a warning for invalid combination of '-mnan' and
'-march' options, it properly sets NaN encoding for a given '-march',
and it passes a proper NaN encoding to the assembler.

Patch by Vladimir Radosavljevic.

Daniel Sanders feb613028b [mips] Invert the abicalls feature bit to be noabicalls so that it's possible for -mno-abicalls to take effect.
Also added the testcase that should have been in r215194.

This behaviour has surprised me a few times now. The problem is that the
generated MipsSubtarget::ParseSubtargetFeatures() contains code like this:

   if ((Bits & Mips::FeatureABICalls) != 0) IsABICalls = true;

so '-abicalls' means 'leave it at the default' and '+abicalls' means 'set it to
true'. In this case, (and the similar -modd-spreg case) I'd like the code to be

  IsABICalls = (Bits & Mips::FeatureABICalls) != 0;

or possibly:

   if ((Bits & Mips::FeatureABICalls) != 0)
     IsABICalls = true;
   else
     IsABICalls = false;

and preferably arrange for 'Bits & Mips::FeatureABICalls' to be true by default
(on some triples).

Daniel Sanders e805f44c8f [mips] Add -mabicalls/-mno-abicalls to the driver
Based on a patch by Matheus Almeida. I've added testcases and fixed a bug where
the options weren't passed on to GAS.

Daniel Sanders 9469417064 [mips] Added -mfp64 and -mfp32 options.
These options specify 64-bit FP registers and 32-bit FP registers respectively.

When using -mfp32, the FPU has 16x double-precision registers overlapping with
the 32x single-precision registers (each double-precision register overlaps
two single-precision registers).

When using -mfp64, the FPU has 32x double-precision registers overlapping with
the 32x single-precision registers (each double-precision register overlaps
with one single-precision register and has an additional 32-bits).

MSA requires -mfp64.

Jack Carter 44ff1e5673 [Mips] MSA frontend option support
This patch adds -mmsa and -mno-msa to the options supported by 
clang to enable and disable support for MSA.

When MSA is enabled, a predefined macro '__mips_msa' is defined to 1.

Jim Grosbach 2987c57924 Tests: check for target availability for target-specific tests.
Lots of tests are using an explicit target triple w/o first checking that the
target is actually available. Add a REQUIRES clause to a bunch of them. This should
hopefully unbreak bots which don't configure w/ all targets enabled.
