Simplify uses of MVT and EVT. An MVT can be compared directly
...
with a SimpleValueType, while an EVT supports equality and
inequality comparisons with SimpleValueType.

Inside the calling convention logic LocVT is always a simple
...
value type, so there is no point in passing it around using
an EVT. Use the simpler MVT everywhere. Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

Two sets of changes. Sorry they are intermingled.
...
1. Fix pre-ra scheduler so it doesn't try to push instructions above calls to
"optimize for latency". Call instructions don't have the right latency and
this is more likely to use introduce spills.
2. Fix if-converter cost function. For ARM, it should use instruction latencies,
not # of micro-ops since multi-latency instructions is completely executed
even when the predicate is false. Also, some instruction will be "slower"
when they are predicated due to the register def becoming implicit input.
