cf42b6a699 Revert r237789 - [mips] The naming convention for private labels is ABI dependant.
It works, but I've noticed that I missed several callers of createMCAsmInfo()
and many don't have a TargetMachine to provide.

571a176b3d [mips] The naming convention for private labels is ABI dependant.
Summary:
For N32/N64, private labels begin with '.L' but for O32 they begin with '$'.

MCAsmInfo now has an initializer function which can be used to provide information from the TargetMachine to control the assembly syntax.

742e6aefa1 [mips] Make mips64 the default CPU for the mips64 architecture
Summary:
This is consistent with the integrated assembler.
All mips64 codegen tests previously passed -mcpu. Removed -mcpu from
blez_bgez.ll and const-mult.ll to cover the default case.

Ideally, the two implementations of selectMipsCPU() will be merged but it's
proven difficult to find a home for the function that doesn't cause link errors.
For now, we'll hoist the common functionality into a function and mark it with
FIXME's.

3ae734a60c Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion.
This was done with the following sed invocation to catch label lines demarking function boundaries:
    sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll
which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct.
