1503988bb5 Modified VNInfo. The "copy" member is now a union which holds the copy for a register interval, or the defining register for a stack interval. Access is via getCopy/setCopy and getReg/setReg.

f64bbe9328 Fix a bug in the DAGCombiner's handling of multiple linked 
MERGE_VALUES nodes. Replacing the result values with the
operands in one MERGE_VALUES node may cause another
MERGE_VALUES node be CSE'd with the first one, and bring
its uses along, so that the first one isn't dead, as this
code expects. Fix this by iterating until the node is
really dead. This fixes PR4699.

49b8a24b7e Fix a weird ppc64-specific link error during an llvm-gcc build: 
ld: bad offset (0x00000091) for lo14 instruction pic-base fix-up in ___popcountdi2 from libgcc/./_popcountsi2_s.o

The problem is that the non lazy symbol pointers need to be 8 byte aligned
on ppc64 and .section doesn't have an implicit alignment like ".non_lazy_symbol_pointer"
does.

91e0e06670 Add support for printing loop structure information in asm comments. 
This definitely slows down asm output so put it under an -asm-exuberant
flag.

This information is useful when doing static analysis of performance
issues.
