I shuffled the fast-isel command-line options around. This fixes
a bunch of fast-isel failures.

If this is the case, and also we want limited precision floating-point
calculations, then lower to do the limited-precision stuff.

the various fast-isel-related command-line options are only used
when -fast-isel itself is enabled.

the target-independent area, with improved comment.

Fix PR2757. Ignore liveinterval register allocation preference if the preference register is not in the right register class. This can happen due to sub-register coalescing.

handle those now, so any that aren't handled should trigger
the abort.

Fix a constant lowering bug. Now we can do load and store instructions with funky getelementptr embedded in the address operand.

objects in llvm.used (thanks Anton).  Makes visible
the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

Reverting r55898 to r55909. One of these patches was causing an ICE during the full bootstrap on Darwin:

the DAG combiner (along with the other arithmetic transformations on constants
