[ARM] Improve generation of thumb stack accesses
Currently when a stack access is out of range of an sp-relative ldr or
str then we jump straight to generating the offset with a literal pool
load or mov32 pseudo-instruction. This patch improves that in two
ways:
* If the offset is within range of sp-relative add plus an ldr then
use that.
* When we use the mov32 pseudo-instruction, if putting part of the
offset into the ldr will simplify the expansion of the mov32 then
do so.
