7ebd32a1b8 Partially revert r89377 by removing NLdStLN class definition from 
ARMInstrFormats.td and fixing VLD[234]LN* and VST[234]LN* to derive from NLdSt
instead of NLdStLN.

ConstantExpr, not just the top-level operator. This allows it to
fold many more constants.

Also, make GlobalOpt call ConstantFoldConstantExpression on
GlobalVariable initializers.

e8e01b600c I forgot to update the prototype for LLVMBuildIntCast when correcting 
the body to not pass the name for the isSigned parameter.  However it
seems that changing prototypes is a big-no-no, so here I revert the
previous change and pass "true" for isSigned, meaning this always does
a signed cast, which was the previous behaviour assuming the name was
not NULL!  Some other C function needs to be introduced for the general
case of signed or unsigned casts.  This hopefully unbreaks the ocaml
binding.

a2f20b20a8 Add getFrameIndexReference() to TargetRegisterInfo, which allows targets to 
tell debug info which base register to use to reference a frame index on a
per-index basis. This is useful, for example, in the presence of dynamic
stack realignment when local variables are indexed via the stack pointer and
stack-based arguments via the frame pointer.

323d8c3ed7 Be more clever about calculating live variables through new basic blocks. 
When splitting a critical edge, the registers live through the edge are:

- Used in a PHI instruction, or
- Live out from the predecessor, and
- Live in to the successor.

This allows the coalescer to eliminate even more phi joins.
