[Tarantool-patches] [PATCH luajit 0/2] Fix tonumber("-0") inconsistencies

[Sergey Kaplun]

This patchset fixes incorrect behaviour for `tonumber("-0")` different
from Lua 5.1.

The first patch fixes it for non-dualnum mode (default on x86 and x64).
The second fixes it for dual-number mode too.
So, there is the corresponding skipcond in the test for the first patch
that is removed in the next patch.
