Log:
Rework block IPA_TM block scanning.

There was a monsterous thinko in bb_in_TM_region, both in its
allocation and initialization.  Split that into a per-cg_data
element transaction_blocks_normal.  Initialize it with the
proper CFG installed.

        * trans-mem.c (struct tm_ipa_cg_data): Add transaction_blocks_normal.
        (bb_in_TM_region): Remove.
        (ipa_tm_scan_calls_block): New.
        (ipa_tm_scan_calls_clone): Use it.
        (ipa_tm_scan_calls_transaction): Likewise.  Initialize
        transaction_blocks_normal.
        (ipa_tm_note_irrevocable): Use transaction_blocks_normal.
        (ipa_tm_propagate_irr): Collect a set of blocks from
        get_tm_region_blocks to use instead of bb_in_TM_region.
        Free the data allocated within the function.
        (ipa_tm_region_init): Remove.
        (ipa_tm_execute): Don't init bb_in_TM_region.  Install the correct
        cfg for use in ipa_tm_scan_calls_transaction.
