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.

Illegal instructions in a slot delay should generate a slot illegal
instruction exception instead of an illegal instruction exception.

The current PC should be saved before generating such an exception,
but should not be corrected if in a delay slot, given it's already
done in the exception handler do_interrupt().

The LDST macro is used to generate ldc and stc instructions that work with a
specific register. However, the SGR register only supports stc up to SH4A,
which supports both stc and ldc. This patch creates two sub-macros named LD
and ST that handle generating ldc and stc instructions separately, and
redeclares LDST to use these sub-macro.

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc9235,
f40d7537,
96555a96 and
3990d09a but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.
