the check to see if the assembler supports .loc from X86TargetLowering
into the superclass TargetLowering.

Added major new capabilities to scheduler (only BURR for now) to support physical register dependency. The BURR scheduler can now backtrace and duplicate instructions in order to avoid "expensive / impossible to copy" values (e.g. status flag EFLAGS for x86) from being clobbered.

bit width instead of number of words allocated, which
makes it actually work for int->APF conversions.
Adjust callers.  Add const to one of the APInt constructors
to prevent surprising match when called with const
argument.

Do not hide APInt::dump() inside #ifndef NDEBUG.

APInt::dump() is inside #ifndef NDEBUG, however SelectionDAG dump() routines are not.

Add a new DenseMapInfo::isEqual method to allow clients to redefine
the equality predicate used when probing the hash table.

Make APInt::dump() public, remove newline, use it to

Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).
