07b2982e77 Don't do ARM FoldShiftLdrStr peephole optimization if there's an offset in the reference.
Use UXTH+UXTB instructions instead of two shifts on processors that supports that.
Eliminate internalerror when constant pointers are typecast as arrays.

81517fdf70 Rerun peephole optimizers on the whole block
Up until now if a peephole optimizer matched we've only restarted from
the current instruction. This patch restarts optimizations on the whole
block if the previous run had at least one match.

As this can take considerable time this will only be enabled if -O3 or
higher is specified.

3f8549365a Don't schedule LDRD on ARM
The load scheduler does not handle LDRD correctly right now, but it does
not prevent A_LDR with PF_D set from beeing scheduled.

57ff589ec7 Always set p to the next instruction after removing p from asml.
Some time ago we introduced GetNextInstructionUsingReg, which might
return an instruction a couple of instructions away from our current
location. Most of the code then just returned the new instruction (hp1)
instead of the instruction following p. This could prevent the peephole
optimizer from finding possible optimizations.

c644503daf Add MovLdr2Ldr peephole optimizer for ARM
The existing LdrLdr2LdrMov optimizer will generate a lot of
sequences like this:

ldr regA, [...]
mov regB, regA
ldr regB, [regB, ...]

this now gets changed to

ldr regA, [...]
ldr regB, [regA, ...]

this saves an instruction and might open up more possibilities for the load scheduler.

77d12f61a2 Handle LDRD and STRD correctly in RegInInstruction for ARM
LDRD and STRD only have the first even numbered register in their instruction operands,
this additional code will also check for the register following it.
Example:
  ldrd r0, [r13]

The old code will only detect r0 as in use, not the implicit r1.
