Summary: [AVX] crash in generated code due to %rbp being
clobbered

test case
I'm seeing a crash upon exiting the _mandelbrot_ispc function defined in the
attached test case. Upon examination, it turns out that %rbp is 0x0, such that
things go south upon the following at the end:
mov %rbp, %rsp
pop %rbp
The issue seems to be that %ebp has been used as a temporary register in the
vmovmskps %ymm12, %ebp
instruction at line 242 in the attached assembly file.
