Implement alloca for x86 (grischka case_8).
This implements alloca() on x86, at least for non-Windows.
Unlike the grischka version, this patch handles both the bounded and
non-bounded cases (when bounded, the alloca'd memory is covered), and
when asked to allocate with 0 size, it returns 0 without any allocation.
Modify the assembly files to adjust the amount of padding (the unused space
after an allocation); this must be at least 1 for bounds-checking. It's
recommended that the padding be identical for unchecked and bounded cases,
because otherwise turning on bound-checking might change errors to non-errors.
