e4dd7378d0 Optimize generated code for integer materialization a bit.

1462777017 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.

f5dda01f33 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.

c63d846ad6 Invert these branches by default, it makes assembly comparisons a little

b2abb508ae Remove an assert - it's possible to be hit, and we just want to avoid 
handling those cases for now.

to what someone would need to do to support thumb1.

338de3ee56 Refactor ARM STR/STRB instruction patterns into STR{B}i12 and STR{B}rs, like 
the LDR instructions have. This makes the literal/register forms of the
instructions explicit and allows us to assign scheduling itineraries
appropriately. rdar://8477752

1e4d9a17c2 First part of refactoring ARM addrmode2 (load/store) instructions to be more 
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

73bc5b0f86 More load/store refactoring, call reg+offset simplification from within 
the emitter to handle the addresses. Only simplify the offset if we need
to - also fix bug where in addrmode 5 we weren't dividing the offset by
4, which showed up due to not always lowering.
