find dynamic stack allocations in checkstack.pl
Currently, checkstack.pl only looks for fixed subtractions from the stack
pointer. However, things like this:
void function(int size)
{
char stackbuster[size << 2];
...
are certainly worth pointing out, I think.
This could perhaps be done more cleanly, and the following patch only
adds "dynamic" REs for x86 and x86_64, but it works:
0x00b0 crypto_cbc_decrypt_inplace [cbc]: Dynamic (%rax)
0x00ad crypto_pcbc_decrypt_inplace [pcbc]: Dynamic (%rax)
0x02f6 crypto_pcbc_encrypt_inplace [pcbc]: Dynamic (%rax)
0x036c _crypto_xcbc_digest_setkey [xcbc]: Dynamic (%rax)
...
(Inspired by Keith Owens' old stack-check script)
