perf/signal: rewrite code in assembly to avoid compiler optimizations
Without this change, the assembly code of this test compiled without
optimizations:
mov -0x150(%rbp),%rax
movl $0x77777777,(%rax)
lea -0x128(%rbp),%rax
with optimizations:
movl $0x77777777,0x0
This code doesn't work properly, because the test changes rax in the segv
handler.
