7ab65934a0 The X86 instruction selector already handles codegen of:
store float 123.45, float* %P

as an integer store.  This adds handling of float immediate stores as integers
for arguments passed function calls.

This is now tested by CodeGen/X86/store-fp-constant.ll

18ad19488d Allow the selection-dag based selector to be diabled with -disable-pattern-isel.
For now, this is the default, as the current selector is missing some big pieces.
To enable the new selector, pass -disable-pattern-isel=false to llc or lli.

5384b38ccc 1. If a double FP constant must be put into a constant pool, but it can be
precisely represented as a float, put it into the constant pool as a
   float.
2. Use the cbw/cwd/cdq instructions instead of an explicit SAR for signed
   division.
