Chris Lattner 7f1fa8eaef implement the other half of the select_cc -> fsel lowering, which handles 
when the RHS of the comparison is 0.0.  Turn this on by default.

Chris Lattner c30405e0ee Change ConstantPoolSDNode to actually hold the Constant itself instead of 
putting it into the constant pool.  This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.

Chris Lattner 2091a36631 Fix a huge annoyance: SelectNodeTo took types before the opcode unlike 
every other SD API.  Fix it to take the opcode before the types.

Chris Lattner f3d06c6417 add initial support for converting select_cc -> fsel in the legalizer 
instead of in the backend.  This currently handles fsel cases with registers,
but doesn't have the 0.0 and -0.0 optimization enabled yet.

Once this is finished, special hack for fp immediates can go away.

Reid Spencer 53846bcdb6 For PR614: 
Move the implementation of the fix from Makefile.rules to Makefile. This
ensures that it is only checked on a top-level rebuild, and not in every
single subdirectory. This removes some annoying messages from the build and
numerous executions of config.status if the .in file changes but not
substantively enough to cause the .h file to be modified by config.status.

Chris Lattner 4ae278a760 LFS/STFS load and store FP values, not integer ones. This change allows us 
to codegen this: float foo() { return 1.245; }

into this:

_foo:
        lis r2, ha16(.CPI_foo_0)
        lfs f1, lo16(.CPI_foo_0)(r2)
        blr

instead of this:

_foo:
        lis r2, ha16(.CPI_foo_0)
        lfs r2, lo16(.CPI_foo_0)(r2)   <-- ouch
        or f1, r2, r2                  <-- ouch
        blr

with the dag isel.
