Add switch and comparison tests. Fix ralloc bug

We normally have 5 registers in our temp pool, but up to 6 may be
needed for long 3-operand operations.  Added a workaround to temporarily
add lr to the temp pool in that specific case.

Moved the bulk of the compiler_test code out of common_test.h into
compiler_test.h.  Added switch and compare unit tests.
