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
ldr r0, [IP, #12]
Before this CL:
add IP. r[Array], #12
ldr r0, [IP, r[Index0], LSL #2]
add IP. r[Array], #12
ldr r0, [IP, r[Index1], LSL #2]
After this CL:
add IP. r[Array], #12
ldr r0, [IP, r[Index0], LSL #2]
ldr r0, [IP, r[Index1], LSL #2]

Test: Run ART test suite on Nexus 6.
