e32ab4bd47 1ULL << 64 is undefined, don't do it.

473ec492f7 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

924f3326e7 Cleanup a bunch of tests. In particular do not allow target directives in 
the .ll file or it forces the V9 backend.  This is the CodeGen/Generic dir,
so there is no use in doing that.

2c398fc8f6 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.
