radv: fix emitting descriptor pointers with LLVM < 7
This was terribly wrong, I forced use of 32-bit pointers when
emitting shader descriptor pointers. This fixes GPU hangs with
LLVM 5&6 because 32-bit pointers are only supported with LLVM 7.
Fixes: 88d1ed0f81 ("radv: emit shader descriptor pointers consecutively")
