60ccc3b0ec [mips] Fix a bug in MipsLongBranch::replaceBranch, which was erasing 
instructions in delay slots along with the original branch instructions.

5c87b732f2 [mips] Use register number instead of name to print register $AT.

273956d8c6 Fix mips' long branch pass. 
Instructions emitted to compute branch offsets now use immediate operands
instead of symbolic labels. This change was needed because there were problems
when R_MIPS_HI16/LO16 relocations were used to make shared objects.

60287963c7 Fix Mips long branch pass. 
This pass no longer requires that the global pointer value be saved to the
stack or register since it uses bal instruction to compute branch distance.
