428b92eb83 Keep track of the start of MBB's in a separate map from instructions. This
is faster and is needed for future improvements.

d6594ae54c Added support for machine specific constantpool values. These are useful for
representing expressions that can only be resolved at link time, etc.

94be248dbb First pass at supporting relocations. Relocations are written correctly to
the file now, however the relocated address is currently wrong.  Fixing
that will require some deep pondering.

6d8fbef015 Teach the coallescer to coallesce live intervals joined by an arbitrary
number of copies, potentially defining live ranges that appear to have
differing value numbers that become identical when coallsced.  Among other
things, this fixes CodeGen/X86/shift-coalesce.ll and PR687.

f7da2c7b0c Take advantage of the recent improvements to the liveintervals set (tracking
instructions which define each value#) to simplify and improve the coallescer.
In particular, this patch:

1. Implements iterative coallescing.
2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a
   better solution.
3. Implements PR865, "coallescing" away the second copy in code like:

   A = B
   ...
   B = A

This also includes changes to symbolically print registers in intervals
when possible.

This reduces selectiondag time on kc++ from 5.43s to 4.98s (9%).  More

a 33% speedup.
