Hi,

This patch series is to fix PR target/64761 which is formally a 4.9/5
regression.  The fix is splitted into 3 pieces:

[PATCH 1/3] Replace MD_REDIRECT_BRANCH with TARGET_CAN_FOLLOW_JUMP
[PATCH 2/3] [SH] Add jump insn for -freorder-blocks-and-partition
[PATCH 3/3] Fix dbr_schedule for -freorder-blocks-and-partition

The patches are tested on sh4-unknown-linux-gnu and i686-pc-linux-gnu
with "make -k check" and "make info dvi pdf".  Also tested on arc-elf32
because arc is another user of TARGET_CAN_FOLLOW_JUMP, though I could
test it with --enable-languages=c only.  For arc-elf32, I've got

Old tests that failed, that have disappeared: (Eeek!)

arc-sim: gcc.dg/tree-prof/20041218-1.c compilation,  -fprofile-use -D_PROFILE_USE

with compare_tests for unpatched/patched trunk compilers.
