Use getRegForValue() to materialize the address of ARM globals.
...
This enables basic local CSE, giving us 20% smaller code for
consumer-typeset in -O0 builds.

Use movw+movt in ARMFastISel::ARMMaterializeGV.
...
This eliminates a lot of constant pool entries for -O0 builds of code
with many global variable accesses.
This speeds up -O0 codegen of consumer-typeset by 2x because the
constant island pass no longer has to look at thousands of constant pool
entries.

The order in which the predicate is added differs between Thumb and ARM mode. Fix predicate when in ARM mode and restore SelectIntrinsicCall.
