This would likely need to be embedded into emit_store_flag and friends. It
would also assume that the target does something sensible for expansion.
What gets passed to emit_store_flag is (leu (reg) (const_int 0xfffff)), which
at least on RISC-V would be better expressed as (ltu (reg) (const_int 0x100000)
which we'd want to realize is expressable by shifting reg and the constant
right to drop the trailing zeros ultimately resulting in a srli+seq.
