Memory references (`*m` in LLVM IR inline assembly) need a pointer type
starting in LLVM 14. This is a bit inconvenient and requires a new API
in the go-llvm package.
Instead of doing that, I'd like to remove support for memory references
from AsmFull (and possibly AsmFull entirely if possible: it's hard to
use correctly).
This breaks tinygo.org/x/drivers/ws2812 for AVR, ARM, and RISC-V which
need to be updated. Probably using CGo.
