3fdc97d460 Add a new option to indicate we want the code generator to emit code quickly,not spending tons of time microoptimizing it. This is useful for an -O0style of build.

763a62efa6 Add some pattern fragments to simplify the repetitive parts of the patterns 
for some common ops and use them for a few examples.  Andrew, if you like
this, feel free to convert the rest over, if you hate it, feel free to
revert.

a7554852b3 ret 0; works, not much else 
still lots of uglyness.
Maybe calls will come soon.
Fixing the return value of things will be necessary to make alpha work.

d3b3d07c41 Add FP versions of the binary operators, keeping the int and fp worlds seperate. 
Though I have done extensive testing, it is possible that this will break
things in configs I can't test.  Please let me know if this causes a problem
and I'll fix it ASAP.

f32ef9a37f 1. Use SubtargetFeatures in llc/lli. 
2. Propagate feature "string" to all targets.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

a31708e6b3 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.
