c984657c74 Add assertions in MipsLongBranch which check the size of basic blocks.

173192fa71 [mips] Delete MipsFunctionInfo::EmitNOAT. Unconditionally print directive 
"set .noat" so that the assembler doesn't issue warnings when register $AT is
used.

4fb08317af Follow-up patch to r162731. 
Fix a couple of bugs in mips' long branch pass.
This patch was supposed to be committed along with r162731, so I don't have a
new test case.

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.

0bc1adbbc4 Add definitions of two subclasses of MipsInstrInfo, MipsInstrInfo (for mips16), 
and MipsSEInstrInfo (for mips32/64).

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.
