Reduce the entries in a phi before testing it for deadness, because removing the entries might make it dead.

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.
