the two token accessor functions are declared consistently.
Modified the clients of MCAsmParser to reflect this change.

function can support dynamic stack realignment. That's a much easier question
to answer at instruction selection stage than whether the function actually
will have dynamic alignment prologue. This allows the removal of the
stack alignment heuristic pass, and improves code quality for cases where
the heuristic would result in dynamic alignment code being generated when
it was not strictly necessary.

doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.
Some notes:
1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives. I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global. If .globl is
actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
before. If this is undesirable, it should explicitly opt out of these
things by clearing the relevant fields of MCAsmInfo.
This leads to a nice diffstat:

I'm not sure that this is correct, but it causes no test failures,
and just emitting a .comm without protecting its linkage somehow
is surely not right.

This makes a similar code dead in all the other targets, I'll clean it up
in a bit.
This also moves handling of lcomm up before acquisition of a section,
since lcomm never needs a section.

GCC would put weak zero initialized mutable data in the .bss section,
we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits'
section. Fixing this will allow simplifications next up.

simplify and commonize some of the asmprinter logic for globals.
This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

1. TargetLoweringObjectFileMachO should decide if something
goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
the right MCSection, the asmprinters should just emit to the
right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
MAI can have a bool "haszerofill" instead of having the textual
directive to emit.

comments (fast isel, X86). This doesn't seem
to break any functionality, but will introduce
cases where -g affects the generated code. I'll
be fixing that.

the various MOV (register) instructions (16-bit Thumb), including tBRIND (the
indirect branch). Instead of '1', it should be specified as '?', because GPR
only specifies the register class, which includes both hi-and-lo registers.

remove it and change all the code that prints MCSymbols to use
<< instead, which is much simpler and cleaner.

to Mangler. Now MCSymbol just decides whether to slap quotes around
a symbol when printing it.
This also fixes some weirdness where two MCSymbols could be created
for the same symbol, if one needed to be mangled and got mangled to
the other one.

The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine,
but we need it to actually be 4-bytes in the FDE for some platforms. Allow
individual platforms to decide for themselves.

Note that the code wasn't calling DecorateCygMingName

FrameIndexes should be lowered, but the same way as
everything else (target dependent) rather than in a
special hacked way. The lowering needs to be done
