Joel Sing d37624881f cmd/internal/obj/riscv: improve constant construction
Attempt to construct large constants that have a consecutive sequence
of ones from a small negative constant, with a logical right and/or
left shift. This allows for a large range of mask like constants to be
constructed with only two or three instructions, avoiding the need to
load from memory.
