ed2185e171 Convert INSERT_SUBREG to COPY in TwoAddressInstructionPass. 
INSERT_SUBREG will now only appear in SSA machine instructions.

Fix the handling of partial redefs in ProcessImplicitDefs. This is now relevant
since partial redef COPY instructions appear.

9c2e7ca351 Be more forgiving when calculating alias interference for physreg coalescing. 
It is OK for an alias live range to overlap if there is a copy to or from the
physical register. CoalescerPair can work out if the copy is coalescable
independently of the alias.

This means that we can join with the actual destination interval instead of
using the getOrigDstReg() hack. It is no longer necessary to merge clobber
ranges into subregisters.

e9e1215d94 second round of low-level interface squeeze-out: 
making all of CallInst's low-level operand accessors
private

If you get compile errors I strongly urge you to
update your code.


I tried to write the necessary clues into the
header where the compiler may point to, but no
guarantees. It works for my GCC.

You have several options to update your code:

- you can use the v2.8 ArgOperand accessors
- you can go via a temporary CallSite
- you can upcast to, say, User and call its
  low-level accessors if your code is definitely
  operand-order agnostic.

If you run into serious problems, please
comment in below thread (and back out this
revision only if absolutely necessary):

36335be3b9 Fix a major regression on COFF targets introduced by r103267: 'discardable' section means that it is used only during the program load and can be discarded afterwards. 
This way *only* debug sections can be discarded, but not the opposite. Seems like the copy-and-pasto from ELF code, since there it contains the reverse flag ('alloc').
