[Patch : H8300] Fix regressions for bit related instructions

[Kaushik Phatak <Kaushik dot Phatak at kpitcummins dot com>]

Hi,

The following patch generates bit instructions for logical operations
on the H8 target. It also generates instructions in #xx:3 and #xx:4 
immediate addressing modes for H8SX target.

The patch fixes 272 regressions on the H8SX target and overall it
fixes 525 regressions.
The original patch was earlier posted in the following Bugzilla link,
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38091

A few issues that came up have been addressed in this version of the
patch.

The patch "h8300_bit_insn.patch" is attached.
