Make the big switch: Change MCSectionMachO to represent a section *semantically*
...
instead of syntactically as a string. This means that it keeps track of the
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and
"attribute(section)", so we should now start getting errors about invalid
section attributes from the compiler instead of the assembler on darwin.
Still todo:
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
S_GB_ZEROFILL segment type?

llvm-mc/AsmParser: Add hack to ignore Int_* and *_Int instructions for now, to
...
make it easier to see interesting ambiguities.
- Also, check that user doesn't try to redefine the super class. This is a wart
in the current design, in that assembler match classes aren't explicitly
declared somewhere (so there isn't a unique place to declare the super
class). This should probably be fixed.

llvm-mc/AsmParser: Separate instruction ordering for ambiguity detection.
...
- We want the ordering operation to be simple, since we run it on every
match. The old ordering is also not a strict weak ordering when there are
ambiguities, which makes MSVC unhappy.
- While we are at it, detect all ambiguities instead of just the adjacent
ones. There are actually 655, for X86.
