slightly to make it easier to read.

Pass the type of the store access, not the type of the store, into the
...
target hook. This allows us to codegen a loop as:
LBB1_1: @cond_next
mov r2, #0
str r2, [r0, +r3, lsl #2 ]
add r3, r3, #1
cmn r3, #1
bne LBB1_1 @cond_next
instead of:
LBB1_1: @cond_next
mov r2, #0
str r2, [r0], #+4
add r3, r3, #1
cmn r3, #1
bne LBB1_1 @cond_next
This looks the same, but has one fewer induction variable (and therefore,
one fewer register) live in the loop.

addi r2, r2, 1
stw r4, 0(r3)
addi r3, r3, 4
cmpwi cr0, r2, -1

instead of:
LBB1_1: ;cond_next
addi r2, r2, 1
li r4, 0
xoris r5, r2, 65535
stw r4, 0(r3)
addi r3, r3, 4
