64-bit prep
Preparation for 64-bit roll.
o Eliminated storing pointers in 32-bit int slots in LIR.
o General size reductions of common structures to reduce impact
of doubled pointer sizes:
- BasicBlock struct was 72 bytes, now is 48.
- MIR struct was 72 bytes, now is 64.
- RegLocation was 12 bytes, now is 8.
o Generally replaced uses of BasicBlock* pointers with 16-bit Ids.
o Replaced several doubly-linked lists with singly-linked to save
one stored pointer per node.
o We had quite a few uses of uintptr_t's that were a holdover from
the JIT (which used pointers to mapped dex & actual code cache
addresses rather than trace-relative offsets). Replaced those with
uint32_t's.
o Clean up handling of embedded data for switch tables and array data.
o Miscellaneous cleanup.
I anticipate one or two additional CLs to reduce the size of MIR and LIR
structs.
