GLIBCXX_DEBUG issues.

Emit proper "secrel" directive, where possible. This fixes invalid asm syntax of debug info on mingw32. Also, cleanup 
some stuff.

Implement some constant folding in SelectionDAG and
DAGCombiner using APFloat.  Remove double versions
of constructor and getValue from ConstantFPSDNode.

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.

llvm-svn: 41640

llvm-svn: 41639

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.

llvm-svn: 41599

llvm-svn: 41598

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.

in the trampoline lowering.  Lookup the jump and
mov opcodes for the trampoline rather than hard
coding them.
