On s390x (gcc-8.3.1-5.1.el8.s390x) the compiler warns that we don't
pass size larger than 2^63-1 to malloc. With LTO enabled, it is also
quite adamant in detecting that with nm_utils_get_next_realloc_size().
Optimally, we would disable this useless warning with "-Wno-alloc-size-larger-than",
but that seems not to work. So add a workaround in code :(
It's hard to actually workaround the warning while handling all kinds of
sizes. The only simple solution is to no handle such huge cases and only
assert.
