Use std::map instead of a (potentially very sparse) array to track val# defined by copy from the other live range. Minor compile time win when number of val# is large.

Use APFloat interfaces for more references, mostly
of ConstantFPSDNode.

Comments added. It now generates V5TE multiply instructions. However, it is still necessary to model PUWLSH bits more clearly.

Added support to fold X86 load / store instructions. This allow rematerialized loads to be folded into their uses.

Add a variant of foldMemoryOperand to fold any load / store, not just load / store from / to stack slots.

Add APFloat interfaces to ConstantFP, SelectionDAG.
Fix integer bit in double->APFloat conversion.
Convert LegalizeDAG to use APFloat interface in
ConstantFPSDNode uses.

Changes related modules so VNInfo's are not copied. This decrease
copy coalescing time by 45% and overall compilation time by 10% on siod.

mov opcodes for the trampoline rather than hard
coding them.

1. Eliminate the costly live interval "swapping".
2. Change ValueNumberInfo container from SmallVector to std::vector. The former
   performs slowly when the vector size is very large.

Changed the stack frame layout, StackGrowsUp fits better to Mips strange stack.
Stack offset calculation bug fixed!

llvm-svn: 41529

Added comments about new stack allocation.
Expand SelectCC for i32 results
