  [X86] Remove regcall calling convention from fp-strict-scalar.ll. Add 32-bit and 64-bit check prefixes.

The regcall was making 32-bit mode pass things in xmm registers
which made 32-bit and 64-bit more similar. But I have upcoming
patches that require them to be separated anyway.

  Log Message:
  -----------
  [X86] Mark vector STRICT_FADD/STRICT_FSUB as Legal and add mutation to X86ISelDAGToDAG

The prevents LegalizeVectorOps from scalarizing them. We'll need
to remove the X86 mutation code when we add isel patterns.

  Log Message:
  -----------
  [LegalizeDAG][X86] Add support for turning STRICT_FADD/SUB/MUL/DIV into libcalls. Use it for fp128 on x86-64.

This requires a minor hack for f32/f64 strict fadd/fsub to avoid
turning those into libcalls.
