target-sh4: optimize exceptions

As exception is not the normal path, don't bother saving PC, before
raising one, instead rely on code retranslation to get the CPU state.

target-sh4: simplify comparisons after a 'and' op

When a TCG variable is anded with a value and the compared with the same
value, we can simply invert the comparison and compare it with 0. The
generated code is smaller.
