Log:
        * cgraph.h (cgraph_local_info): Add tm_may_enter_irr.
        * gimple-pretty-print.c (dump_gimple_tm_atomic_subcode): Rename
        GTMA_MUST_CALL_IRREVOKABLE to GTMA_DOES_GO_IRREVOKABLE.
        * trans-mem.c (expand_call_tm): Handle irrevocability.
        (execute_tm_mark): Set GTMA_DOES_GO_IRREVOKABLE and
        GTMA_MAY_ENTER_IRREVOKABLE.
        (expand_tm_atomic): Set PR_DOESGOIRREVOKABLE,
        PR_UNINSTRUMENTEDCODE, and PR_HASNOIRREVOKABLE appropriately.
        (ipa_tm_scan_calls_tm_atomic): Set tm_may_enter_irr for
        replacement functions.
        (ipa_tm_scan_calls_clone): Same.
        (ipa_tm_transform_tm_atomic): If the block goes irrevocable, don't
        transform anything.
        (ipa_tm_transform_clone): Set tm_may_enter_irr for non safe
        functions.
        (ipa_tm_execute): Set tm_may_enter_irr for non-local tm_callable
        functions. Swap loops calling ipa_tm_transform_clone and
        ipa_tm_transform_tm_atomic.
        * gimple.h: Rename GTMA_MUST_CALL_IRREVOKABLE into
        GTMA_DOES_GO_IRREVOKABLE.
