LoongArch: Add new code model 'medium'.
The function jump instruction in normal mode is 'bl',
so the scope of the function jump is +-128MB.
Now we've added support for 'medium' mode, this mode is
to complete the function jump through two instructions:
pcalau12i + jirl
So in this mode the function jump range is increased to +-2GB.
Compared with 'normal' mode, 'medium' mode only affects the
jump range of functions.
