3b24c01720 make MergeableCString be a SectionKind "abstract class", and 
add new concrete versions for 1/2/4-byte mergable strings.

These are not actually created yet.

but masm is already broken.

0144280cfb Unbreak win64 compilation callback. 
Since we're generating stubs by hands we don't follow the ABI and don't
create a register spill area.
Don't use this area in compilation callback!

3bb9b9a1ab The x86 jit doesn't generate a def_cfa_offset unwind instruction after the 
pushes in the function prolog if the function doesn't have any stack space,
i.e. for a prolog like:

0x40011870:     push %r15
0x40011872:     push %r14
0x40011874:     push %rbx

normalize this to match other targets.

d90183d25d Move the getInlineAsmLength virtual method from TAI to TII, where 
the only real caller (GetFunctionSizeInBytes) uses it.

The custom ARM implementation of this is basically reimplementing
an assembler poorly for negligible gain.  It should be removed 
IMNSHO, but I'll leave that to ARMish folks to decide.

d5bbb07ec8 move getDwarfExceptionSection from TAI to TLOF and rename it to 
getLSDASection() to be more specific.  This makes it pretty obvious
that the ELF LSDA section is being specified wrong in PIC mode.  We're
probably getting a lot of startup-time relocations to a readonly page,
which is expensive and bad.

Someone who cares about ELF C++ should investigate this.

83d77faf6e Remove "JumpTableDataSection" from TAI, instead, have AsmPrinter 
compute it based on what it knows.  As part of this, rename getSectionForMergeableConstant
to getSectionForConstant because it works for non-mergable constants also.

The only functionality change from this is that Xcore will start dropping
its jump tables into readonly section instead of data section in -static mode.
This should be fine as the linker resolves the relocations.  If this is a
problem, let me know and we'll come up with another solution.

c09e411102 llvm-mc: A few more parsing / match tweaks. 
- Operands which are just a label should be parsed as immediates, not memory
   operands (from the assembler perspective).

 - Match a few more flavors of immediates.

 - Distinguish match functions for memory operands which don't take a segment
   register.

 - We match the .s for "hello world" now!

a027d222e1 llvm-mc: Match a few X86 instructions. 
- This is "experimental" code, I am feeling my way around and working out the
   best way to do things (and learning tblgen in the process). Comments welcome,
   but keep in mind this stuff will change radically.

 - This is enough to match "subb" and friends, but not much else. The next step is to
   automatically generate the matchers for individual operands.
