Because I was working on multiple things at once, this commit also: - Adds wrappers for/linker flags to wrap CXX exceptions to make them abort. This saves ~0x8000 of memory in every system module. - Broadly replaces lines of the pattern if (cond) { return ResultX; } with R_UNLESS(!cond, ResultX());. - Reworks the R_TRY_CATCH macros (and the result macros in general).
