[X86] Use single add/sub for large stack offsets
For large stack offsets the compiler generates multiple immediate mode
sub/add instructions in the prologue/epilogue. This patch makes the
compiler place the final amount to be added/subtracted into a register,
which is then added/substracted with a single operation.
