MCRelaxableFragment previously kept a copy of MCSubtargetInfo and
MCInst to enable re-encoding the MCInst later during relaxation. A copy
of MCSubtargetInfo (instead of a reference or pointer) was needed
because the feature bits could be modified by the parser.
This commit replaces the MCSubtargetInfo copy in MCRelaxableFragment
with a constant reference to MCSubtargetInfo. The copies of
MCSubtargetInfo are kept in MCContext, and the target parsers are now
responsible for asking MCContext to provide a copy whenever the feature
bits of MCSubtargetInfo have to be toggled.
With this patch, I saw a 4% reduction in peak memory usage when I
compiled verify-uselistorder.lto.bc using llc.

MCSubtargetInfo in the subclasses into MCTargetAsmParser and define a
member function getSTI.
This is done in preparation for making changes to shrink the size of
MCRelaxableFragment. (see http://reviews.llvm.org/D14346).

The printed name and the parsed assembler names weren't the same.
I'm not sure which name SC prints these as, but I think it's this one.

If the requested SGPR was not actually aligned, it was
accepted and rounded down instead of rejected.
Also fix an assert if the range is an invalid size.

Summary:
The assembly printing of these is still missing the encoding size
suffix, but this will be fixed in a later commit.

Adds vcc to output string input for e32. Allows option
of using e64 encoding with assembler.
Also fixes these instructions not implicitly reading exec.

represented by uint64_t, this patch replaces these
usages with the FeatureBitset (std::bitset) type.
