    [PR99123] inline-asm: Don't use decompose_mem_address to find used hard
regs

    Inline asm in question has empty constraint which means anything
    including memory with invalid address.  To check used hard regs we
    used decompose_mem_address which assumes memory with valid address.
    The patch implements the same semantics without assuming valid
    addresses.

            PR inline-asm/99123
            * lra-constraints.c (uses_hard_regs_p): Don't use
decompose_mem_address.
