SPU section handling is really huge mess. Replace remaining TAI calls for sections with explicit names in order not to block existing backends during section handling migration. SPU folks! Please consider using new section handling facility someday.

Properly handle 'm' inline asm constraints. If a GV is being selected for the addressing mode, it requires the same logic for PIC relative addressing, etc.

causes Fast-ISel to leave behind lots of dead instructions.
Those will be dealt with in subsequent commits.

over having it in a register. And wait until after checking type
legality before requesting that the callee address be placed in a
register. Also, fix support for calls with void return type.

This speeds up fast-isel isel time by about 15% and reduces
instruction counts by about 3% overall on certain testcases. It also
changes many indirect calls to direct calls.
