Fix a bug in my patch for legalizing to fsel. It cannot handle seteq/setne,
...
which I failed to include when I moved the code over. This fixes
MallocBench/gs.

Fix some really strange indentation that xcode likes to use.
...
no xcode, this is not right:
if (!foo) break;
X;

Make fsel emission work with both the pattern and dag-dag selectors, by
...
giving it a non-instruction opcode. The dag->dag selector used to not
select the operands of the fsel, because it thought that whole tree was
already selected.

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.

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.

subregs.

Implement BR_CC and BRTWOWAY_CC. This allows the removal of a rather nasty

fixme from the PowerPC backend. Emit slightly better code for legalizing
