Log Message:
Define the mcount function in assembler, and have it save all registers
used for argument passing, plus %rax (used to pass the number of float
arguments to varargs functions), to avoid having it clobber caller-saved
registers. mcount is emitted "under the radar", so the compiler doesn't
know it should do this.

Change the kernel mcount entry/exit macros to use plain cli/sti, like on i386.
