convert many uses of pointer_map to hash_map
gcc/c-family/
* cilk.c: Use hash_map instead of pointer_map.
gcc/c/
* c-typeck.c: Use hash_map instead of pointer_map.
gcc/cp/
* optimize.c, semantics.c: Use hash_map instead of pointer_map.
gcc/
* hash-map.h (default_hashmap_traits::mark_key_deleted):
Fix cast.
(hash_map::remove): New method.
(hash_map::traverse): New method.
* cgraph.h, except.c, except.h, gimple-ssa-strength-reduction.c,
ipa-utils.c, lto-cgraph.c, lto-streamer.h, omp-low.c, predict.c,
tree-cfg.c, tree-cfgcleanup.c, tree-eh.c, tree-eh.h, tree-inline.c,
tree-inline.h, tree-nested.c, tree-sra.c, tree-ssa-loop-im.c,
tree-ssa-loop-ivopts.c, tree-ssa-reassoc.c, tree-ssa-structalias.c,
tree-ssa.c, tree-ssa.h, var-tracking.c: Use hash_map instead of
pointer_map.
