* tree-inline.h (eni_weights): Add field target_builtin_cost to
reflect the cost per call to a target specific builtin.
* tree-inline.c (estimate_num_insns_1): If it is a CALL_EXPR for
* a
call to a target specific builtin, then use
target_builtin_call_cost.
(init_inline_once): Initialize target_builtin_call_cost field.
