Erik Eckstein 2b9b2d243c Optimizer: improve TempLValueOpt ...

* re-implement the pass in swift
* support alloc_stack liveranges which span over multiple basic blocks
* support `load`-`store` pairs, copying from the alloc_stack (in addition to `copy_addr`)

Those improvements help to reduce temporary stack allocations, especially for InlineArrays.
