[fast-isel] Fold "urem x, pow2" -> "and x, pow2-1". This should fix the 271%
...
execution-time regression for nsieve-bits on the ARMv7 -O0 -g nightly tester.
This may also improve compile-time on architectures that would otherwise
generate a libcall for urem (e.g., ARM) or fall back to the DAG selector.

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.

Simplify printing of ARM shifted immediates.
...
Print shifted immediate values directly rather than as a payload+shifter
value pair. This makes for more readable output assembly code, simplifies
the instruction printer, and is consistent with how Thumb immediates are
displayed.

Rewrite fast-isel integer cast handling to handle more cases, and to be simpler and more consistent.
...
The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts).
