JIT: Combine add with shift and offset for array load & store.

Optimize long and double array load / store for ARM JIT.
Array load / store performs a logical shift left and add,
replace it with add capable of performing shift in the
same instruction.
Array load / store performs an add instead of using offset
for vldr/vstr. Replace the add and vldr/vstr with a vldr/vstr
that is capable of handling offset.

This improves performance for usecases involving long and double
array code execution in Dalvik. E.g WindowOrientation.

JIT: Combine shift & sub for monitor unlock.

Optimize monitor unlock for ARM Thumb2 JIT.
Monitor unlock performs a logical shift left
and sub, replace it with a sub capable of
performing the shift in the same instruction.

This improves performance for usecases involving code
executing in Dalvik.

JIT: Use vmla.f64 instead of vmuld + vaddd.

Optimize Java double floating-point performance for ARM JIT.
Whenever a double mul is followed with a double add,
replace it with a combined mul and add instruction.

This improves double arithmetic performance for code executing
in Dalvik.

JIT: Allow use of cbz/cbnz for conditional branch gen.

Optimize conditional branch generation when comparing
with zero for ARM JIT. When possible use cbz/cbnz
instead of cmp+beq/cmp+bne.

This improves performance for usecases involving
code execution in Dalvik.

JIT: Use rsb and shift in easy multiply.

For easy multiplication using reverse subtract (when
lit is 2^n-1) use the barrel shifter for rsb.

This improves arithmetic performance for code executing
in Dalvik. E.g String.hashCode.

JIT: Suppress loop suspend checks.

Suppresses the suspend checks generated by the JIT compiler,
for small loops. This improves performance and code size of loops.

JIT: Hoist loop load operations above loop.

Hoists Dalvik frame load operations outside of loops, when possible.
This improves performance in most loops, and is noticable in many
applications.
