flags.h, [...]: Remove flag_alias_check; optimization is now always enabled.
* flags.h, toplev.c, calls.c, alias.c: Remove flag_alias_check;
optimization is now always enabled.
* calls.c (expand_call): Recognize C++ operator new as malloc-like
function.
* alias.c (memrefs_conflict_p): Eliminate tests now done by
base_alias_check.
(*_dependence): Call canon_rtx before base_alias_check.
(init_alias_once): New function to precompute set of registers which
can hold Pmode function arguments.
* rtl.h: Declare init_alias_once.
* toplev.c (compile_file): Call init_alias_once.
