i386: Redefine indirect_thunks_used as HARD_REG_SET.
Change indirect_thunks_used to HARD_REG_SET to avoid recalculations
of correct register numbers and allow usage of SET/TEST_HARD_REG_BIT
accessors.
2021-11-17 Uroš Bizjak <ubizjak@gmail.com>
gcc/ChangeLog:
* config/i386/i386.c (indirect_thunks_used): Redefine as HARD_REG_SET.
(ix86_code_end): Use TEST_HARD_REG_BIT on indirect_thunks_used.
(ix86_output_indirect_branch_via_reg): Use SET_HARD_REG_BIT
on indirect_thunks_used.
(ix86_output_indirect_function_return): Ditto.
