they are registers.
Fixes bugs exposed by improved alias propagation code.
* alias.c (new_reg_base_value): New array of potential base values.

a REG, try to get its base value. Handle base + index and
index + base.

(schedule_block): Initialize reg_last_uses_size.
(schedule_insns): Always call init_alias_analysis.
* calls.c (expand_call): Note calls to malloc, calloc, and realloc;
mark return value from such functions as a pointer and keep track of
them for alias analysis. If a return value from a function is a
pointer, mark it as such.
* combine.c (distribute_notes): Handle REG_NOALIAS.
* cse.c (struct write_data): Delete. No longer needed.
(invalidate): Don't call set_nonvarying_address_components anymore.
