Small optimization in 'luaH_psetint'
It is quite common to write to empty but existing cells in the array
part of a table, so 'luaH_psetint' checks for the common case that
the table doesn't have a newindex metamethod to complete the write.

Optimizations for 'lua_rawgeti' and 'lua_rawseti'
'lua_rawgeti' now uses "fast track"; 'lua_rawseti' still calls
'luaH_setint', but the latter was recoded to avoid extra overhead
when writing to the array part after 'alimit'.

Bug: Yielding in a hook stops in the wrong instruction
Yielding in a hook must decrease the program counter, because it already
counted an instruction that, in the end, was not executed. However,
that decrement should be done only when about to restart the thread.
Otherwise, inspecting the thread with the debug library shows it one
instruction behind of where it really is.

Removed compatibility option LUA_COMPAT_GCPARAMS
The meaning of different GC parameters changed, so there is point in
supporting old values for them. The new code simply ignores the
parameters when changing the GC mode, so the incompatibility is small.

New option "setparms" for 'collectgarbage'
The generational mode also uses the parameters for the incremental
mode in its major collections, so it should be easy to change those
parameters without having to change the GC mode.
