It's not legal to output a GV in a coalesced section if it's used in an ARM PIC relative constantpool.

use the more precise 'op1' instead of 'var1' since the latter can be misunderstood to not encompass constants

Fixed bug in adjustMipsStackFrame, which was breaking
while trying to access a dead stack object index. Also added
one more alignment before fixing the callee saved registers
stack offset adjustment.

Support for soften float fp_round operands is added, Mips 
needs this to round f64->f32.

Also added support to soften float FABS result, Mips doesn't 
support double fabs results while in 'single float only' mode.

Do a dominator walk when scheduling copies, rather than a DFS on the CFG.  Also, fix a few problems when creating
live intervals for temporaries created by phi elimination.
