[Bug middle-end/44291] [4.6 regression] ICE in set_user_assembler_libfunc

I see this error too, it's causing gcc.c-torture/execute/builtins/memops-asm.c
and gcc.dg/pr39443.c to regress on arm-linux-gnueabi due to ICEs.  I didn't see
the problem in 4.6-20100515 (r159445), but do see it in 4.6-20100522 (r159746)
and current head (r160155).  I'll try to bisect this.

An even simpler test case is:

extern void abort (void)
__asm__ (foo_abort)
;

Commenting out the __asm__ bit cures the ICE.

It's caused by r159455:

* lto-symtab.c (lto_symtab_entry_hash): Use IDENTIFIER_HASH_VALUE.
* optabs.c (libfunc_decl_hash): Likewise.

fortran/
* trans-decl.c (module_htab_decls_hash): Use IDENTIFIER_HASH_VALUE.

Reverting just the change to optabs.c eliminates the ICE.

  id = get_identifier (name);
  hash = htab_hash_string (name);

this should be

  hash = IDENTIFIER_HASH_VALUE (id);
