gbdb: change cycle calculation for better performance
...
The conditions are hotpath, so pre-calcuate the end cycle count instead of doing it every loop.
I didn't verify that the compiler wasn't doing this anyway, but this won't hurt.

build: do not use LTO for --perf

LTO results in a significant performance boost, but hurts debugability of the results from perf. For now, disable it.

Makefile: fix stopping on failed tests
...
A previous patch changed the way tests are run by piping the output
into sed to indent the output. This broke checking the return code of
the test because the return code is really that of sed.
Fix this by taking a dependecy on bash and using PIPESTATUS to get
the return code fo the test.

gbemu: refactor testing infrastructure
...
Similar to gbasm, break the testing into different files for sanity's
sake. This patch also adds a "test" register state which is compared
to the state of the actual CPU registers at the end of the test.
Finally, break the inc and dec tests, but add "ld r8, r8" and "ld dr,
d8" tests.

Though not a real register, the operand "(hl)" fits in
better with the 8-bit registers than it does with the
sixteen bit ones. As such, move its definition.
Also, define useful values for the 8-bit operands rather
than arbitrary ones.
