sim: unify platform function & header tests Move the various platform tests up a level to avoid duplication across the ports. When building multiple versions, this speeds things up a bit. For now we move the obvious stuff up a level, but we don't turn own the config.h entirely just yet -- we still have some tests related to libraries that need consideration.

sim: m32r: fixup some of the int<->pointer casts The m32r trap code was written for a 32-bit Linux host (and really, one whose Linux ABI matched pretty exactly). This has lead to conversions between integers and pointers which breaks down hard on 64-bit hosts. Clean up some of the functions where possible to avoid unnecessary conversions, use uintptr_t to cast 32-bit target pointers to host pointers in some places, and just stub out a few functions that can't easily be salvaged currently when sizeof(void*) is not 32-bits. This is a bit ugly, but lets us enable warnings for the whole file.

sim: unify platform function & header tests Move the various platform tests up a level to avoid duplication across the ports. When building multiple versions, this speeds things up a bit. For now we move the obvious stuff up a level, but we don't turn own the config.h entirely just yet -- we still have some tests related to libraries that need consideration.
