Rework the logic that determines if a store completely overlaps an ealier store.
There are two ways that a later store can comletely overlap a previous store:
1. They both start at the same offset, but the earlier store's size is <= the
later's size, or
2. The earlier store's offset is > the later's offset, but it's offset + size
doesn't extend past the later's offset + size.

Nasty bug in ARMBaseInstrInfo::produceSameValue(). The MachineConstantPoolEntry
entries being compared may not be ARMConstantPoolValue. Without checking
whether they are ARMConstantPoolValue first, and if the stars and moons
are aligned properly, the equality test may return true (when the first few
words of two Constants' values happen to be identical) and very bad things can
happen.

Cmp peephole optimization isn't always safe for signed arithmetics.
int tries = INT_MAX;
while (tries > 0) {
tries--;
}
The check should be:
subs r4, #1
cmp r4, #0
bgt LBB0_1
The subs can set the overflow V bit when r4 is INT_MAX+1 (which loop
canonicalization apparently does in this case). cmp #0 would have cleared
it while not changing the N and Z bits. Since BGT is dependent on the V
bit, i.e. (N == V) && !Z, it is not safe to eliminate the cmp #0.
