ca0ea7b9ba Re-fix hiding the Frame Pointer from the register allocator in functions 
that have a frame pointer.  This change fixes Burg.  In addition, make
the necessary changes to floating point code gen and constant loading after
Chris Lattner's fixes to the asm writer.  These changes fix MallocBench/gs

b9ab0ef60d Fix PR422. 
Ouch! Changes in the lazy initialization code caused each incorporated
function to reprocess the entire function on every lookup of a value's
slot number. This caused a horrible slowdown in all functions. This
fix made llvm-dis go from "longer than I care to wait" (minutes) on a large
test case to 0.53 seconds.

00a1951fb1 Fix frame pointer handling: 
Reserve R0 in store/load from stack slot for building >32k offsets from SP
or FP.  This also requires we use R11 rather than R0 for holding the LR
value we want to save or restore.  Also, tell the register allocator not
to use R31 (our FP) in functions that have a frame pointer.  These changes
fix Burg.
