ARM: Port instr simplification of array accesses.
After changing the addressing mode for array accesses (in
https://android-review.googlesource.com/248406) the 'add'
instruction that calculates the base address for the array can be
shared across accesses to the same array.
Before https://android-review.googlesource.com/248406:
add IP, r[Array], r[Index0], LSL #2
ldr r0, [IP, #12]
add IP, r[Array], r[Index1], LSL #2

X86: Use memory to do array range checks
Currently, an HBoundsCheck is fed by an HArrayLength, causing a load of
the array length, followed by a register compare.
Avoid the load when we can by comparing directly with the array length
in memory. Implement this by marking the HArrayLength as 'emitted at
use site', and then generating the code in the HBoundsCheck.
Only do this replacement when we are the only user of the ArrayLength
and it isn't visible to the environment.
Handle the special case where the array is 'null' and where an implicit
null check can't be eliminated.
This code moves the load of the length to the slow code for the failed
check, which is what we want.

Introduce more compact ReadBarrierMark slow-paths.
Replace entry point ReadBarrierMark with 32
ReadBarrierMarkRegX entry points, using register
number X as input and output (instead of the standard
runtime calling convention) to save two moves in Baker's
read barrier mark slow-path code.
Test: ART host and target (ARM, ARM64) tests.

Two more patterns for instruction simplifier
This patch allows the instruction simplifier to cover
two more cases:
x = a + b and x = a - b
y = x - b y = x + b
In both cases y can be replaced with a, if the types
of arguments are integral.
