Fix PR1666, SPASS with the CBE and 254.gap with the CBE.
...
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.

double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.
Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.

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

Initial support for multi-result patterns:
...
1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
(modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.
