This patch marks the X86 floating point stack registers ST0-ST7 as reserved
in order to avoid assertion failures in the register scavenger. The assertion
failures were “Bad machine code: Using an undefined physical register” and
“Bad machine code: MBB exits via unconditional fall-through but its successor
differs from its CFG successor!”.
