9ee4ce2f91 SIToFP and FPToSI conversions work only on fp-reg to fp-reg. Move 
some data around and implement a couple of move routines to do this.

f9a26b89f8 What the loop unroller cares about, rather than just not unrolling loops with calls, is 
not unrolling loops that contain calls that would be better off getting inlined.  This mostly
comes up when an interleaved devirtualization pass has devirtualized a call which the inliner
will inline on a future pass.  Thus, rather than blocking all loops containing calls, add
a metric for "inline candidate calls" and block loops containing those instead.

there seems to be a better way to achieve the same effect.

6add2fbb69 Use code-size reduction metrics to estimate the amount of savings we'll get when we unroll a loop. 
Next step is to recalculate the threshold values given this new heuristic.

5f54ce3473 For each instruction itinerary class, specify the number of micro-ops each 
instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.

This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.

082bf2a977 Refactor code-size reduction estimation methods out of InlineCostAnalyzer and into CodeMetrics. They 
don't use any InlineCostAnalyzer state, and are useful for other clients who don't necessarily want to use
all of InlineCostAnalyzer's logic, some of which is fairly inlining-specific.

No intended functionality change.

operand from the pseudo instruction to the new instruction as an implicit use.

4975447d94 Relax the "don't unroll loops containing calls" rule. Instead, when a loop contains a call, lower the 
unrolling threshold to the optimize-for-size threshold.  Basically, for loops containing calls, unrolling
can still be profitable as long as the loop is REALLY small.
