GCC optimizes away things like ptr < NULL  to false.  To "fix" this,
have the CBE emit casts of pointers to intptr_t when doing relational
pointer comparisons.

Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),

This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.

Similar to #1 except this is used for def : Pat patterns.

Patch by Sterling Stein!

llvm-svn: 41758

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)
