Jake Burkholder 61f869600d Add definitions for statistical and high-resolution profiling. The calling
conventions for _mcount and __cyg_profile_func_enter are different, so
statistical profiling kernels build and link but don't actually work.
IWBNI one could tell gcc to only generate calls to the former.

Define uintfptr_t properly for userland, but not for the kernel (I hope).
