The RISC-V implementations of the `__mulsi3`, `__muldi3` builtins were conditionally compiling the actual function definitions depending on whether the M extension was present or not. This caused Compiler-RT testing failures for RISC-V targets with the M extension, as when these sources were included the `librt_has_mul*i3` features were still being defined. These `librt_has_*` definitions are used to conditionally run the respective tests. Since the actual functions were not being compiled-in, the generic test for `__muldi3` would fail. This patch makes these implementations follow the normal Compiler-RT convention of always including the definition, and conditionally running the respective tests by using the lit conditional `REQUIRES: librt_has_*`. Since the `mulsi3_test.c` wasn't actually RISC-V-specific, this patch also moves it out of the `riscv` directory. It now only depends on `librt_has_mulsi3` to run.
