Save stack space while handling errors
Because error handling (luaG_errormsg) uses slots from EXTRA_STACK,
and some errors can recur (e.g., string overflow while creating an
error message in 'luaG_runerror', or a C-stack overflow before calling
the message handler), the code should use stack slots with parsimony.
This commit fixes the bug "Lua-stack overflow when C stack overflows
while handling an error".
