//! # RCWSCASP, RCWSCASPA, RCWSCASPAL, RCWSCASPL
//!
//! This instruction reads a 128-bit quadword from memory, and compares it against the value held in a pair of registers. If the comparison is equal, the value in a second pair of registers is conditionally written to memory. Storing back to memory is conditional on RCW Checks and RCWS Checks. If the compare fails, the RCW Checks fail, or the RCWS Checks fail, the architecture permits writing the value read from the location to memory. If the write is performed, the read and the write occur atomically such that no other modification of the memory location can take place between the read and the write. This instruction updates the condition flags based on the result of the update of memory.
