This adapts SH's logical right shift patterns to work/look the same way
as left shift patterns. It mainly fixes a few issues with dynamic shift
insn selection.

Hello,
This fixes the case where a dynamic shift would expand into a P27 shift
sequence that clobbers T_REG, which would result in wrong code.

Removing the T_REG clobber from the left shift patterns entirely wasn't
such a good idea. Especially if dynamic shifts are not available
(anything SH3) incorrect code may be generated.

Hello,
In cases where dynamic shifts are available, the ashlsi3_d pattern is
picked first and never converted back to a short sequence of constant
shifts. Preferring short constant shift sequences over dynamic shifts
can potentially reduce the need for an extra register to hold the shift
count.

Hello,
This adjusts the cost calculations for shifts on SH.
I tried out Richard's advice
( http://gcc.gnu.org/ml/gcc-patches/2012-07/msg01206.html )
and it seems to work OK to just leave out the mentioned CONST_INT_P
case.

Hello,
The attached patch reorganizes the SH left shift patterns. The final
generated shift insns don't differ much, but it seems to have some
positive side effects on register allocation in some cases.
