ff6ab17619 Until we have a "ALIGN" pseudo instruction, have asm printer emitted a .align 
to ensure the instruction that follows a TBB (when the number of table entries
is odd) is 2-byte aligned.
Patch by Sandeep Patel.

d26b14c34c - Teach TBB / TBH offset limits are 510 and 131070 respectively since the offset 
is scaled by two.
- Teach GetInstSizeInBytes about TBB and TBH.

ad2afc2a42 Reapply r77654 with a fix: MachineFunctionPass's getAnalysisUsage 
shouldn't do AU.setPreservesCFG(), because even though CodeGen passes
don't modify the LLVM IR CFG, they may modify the MachineFunction CFG,
and passes like MachineLoop are registered with isCFGOnly set to true.

82987bfe9b fix PR4650: we only track sizes for certain objects, so only put something 
into the mergable section if it is one of our special cases.  This could
obviously be improved, but this is the minimal fix and restores us to the
previous behavior.

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.
