Paul E. Murphy dcd018b5c5 cmd/internal/obj/ppc64: generate MOVD mask constants in register
Add a new form of RLDC which maps directly to the ISA definition
of rldc: RLDC Rs, $sh, $mb, Ra. This is used to generate mask
constants described below.

Using MOVD $-1, Rx; RLDC Rx, $sh, $mb, Rx, any mask constant
can be generated. A mask is a contiguous series of 1 bits, which
may wrap.
