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.

clang_getCursor()-related issue with CXXFunctionalCastExprs with
CXXConstructExprs as children (see FIXME in the test case); I'll look
at that separately.

the asmmatcher would just force a 0 register into it, which clearly
isn't right.  Mark a bunch of ARM instructions that use this as 
isCodeGenOnly.  Some of them are clearly pseudo instructions (like
t2TBB) others use a weird hasExtraSrcRegAllocReq thing that will
either need to be removed or the asmmatcher will need to be taught
about it (someday).

VLDR's case). Removing the "12" allows it to be more generic.
