c586d26812 X86: move Int_CVTSD2SSrr, Int_CVTSI2SSrr, Int_CVTSI2SDrr, Int_CVTSS2SDrr from
OpTbl1 to OpTbl2 since they have 3 operands and the last operand can be changed
to a memory operand.

e0b464f291 Use correct loads for vector types during extending-load operations.
Previously, we used VLD1.32 in all cases, however there are both 16 and 64-bit
accesses being selected, so we need to use an appropriate width load in those
cases.

eb74c08192 Add a proper if-conversion cost model.
Detect when there is not enough available ILP, so if-conversion can't
speculate instructions for free.

Compute the lengthening of the critical path when inserting a select
instruction that depends on the condition as well as both sides of the
if.

Reject conversions that would stretch the critical path by more than
half a mispredict penalty.

5413b68b1f Add more trace query functions.
Trace::getResourceLength() computes the number of cycles required to

compared to the critical path to estimate the trace ILP.

Trace::getPHIDepth() computes the data dependency depth of a PHI in a
trace successor that isn't necessarily part of the trace.
