The patch teaches the clang's driver to understand new MIPS ISA names,
pass appropriate options to the assembler, defines corresponding macros etc

It wasn't actually a bug that -mabicalls/-mno-abicalls wasn't being passed to
GAS. The only reason we pass it to the integrated assembler is because it shares
the same framework with CodeGen.

Summary:
As a result of this patch, assembling an empty file with GCC and Clang (using
GAS as the assembler) now produces identical objects.
-mfp32/-mfpxx/-mfp64 now form a trinity of options. -mfpxx is the default
when the triple vendor is 'img' or 'mti', the ABI is O32, and the CPU is
between mips2 and mips32r2/mips64r2 (inclusive).
-mno-shared is always given to the assembler to match the effect of
-mabicalls (currently unimplemented but Clang acts as if it is given).
Similarly, -call_nonpic is always given to match the effect of -mplt (also
unimplemented and acts as if given) except when the ABI is 64 in which case
-mplt has no effect so -KPIC is given instead.
-mhard-float/-msoft-float are now passed on.
-modd-spreg/-mno-odd-spreg are now passed on.
-mno-mips16 is correctly passed on. The assembler option is -no-mips16 not
-mno-mips16

Summary:
This patch adds minimal coverage for each -mcpu value to ensure that none of them can pass an empty string in -mabi.
Prior to r212176, many -mcpu values would trigger this.

Summary:
For example: s/MIPS32-EB-AS/MIPS32R2-EB-AS/ since it is for MIPS32r2 not MIPS32.
This reduces the noise in my next Clang patch.

The tests attempt to validate the invocation of the assembler program with the
integrated assembler disabled. However, the match pattern for the negative
tests are lax and will match both the driver invocation as well as the assembler
invocation. Make the tests more strict by ensuring that we only match the
assembler invocation.
