 // Register Save Types:
 //
 // NS  = No-Save:       The register allocator assumes that these registers
 //                      can be used without saving upon entry to the method, &
 //                      that they do not need to be saved at call sites.
 //
 // SOC = Save-On-Call:  The register allocator assumes that these registers
 //                      can be used without saving upon entry to the method,
 //                      but that they must be saved at call sites.
 //
 // SOE = Save-On-Entry: The register allocator assumes that these registers
 //                      must be saved before using them upon entry to the
 //                      method, but they do not need to be saved at call
 //                      sites.
 //
 // AS  = Always-Save:   The register allocator assumes that these registers
 //                      must be saved before using them upon entry to the
 //                      method, & that they must be saved at call sites.
 //
 // Ideal Register Type is used to determine how to save & restore a
 // register.  Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get
 // spilled with LoadP/StoreP.  If the register supports both, use Op_RegI.
 //
 // The encoding number is the actual bit-pattern placed into the opcodes.
 // XMM registers.  256-bit registers or 8 words each, labeled (a)-h.
 // Word a in each register holds a Float, words ab hold a Double.
 // The whole registers are used in SSE4.2 version intrinsics,
 // array copy stubs and superword operations (see UseSSE42Intrinsics,
 // UseXMMForArrayCopy and UseSuperword flags).
 // XMM8-XMM15 must be encoded with REX (VEX for UseAVX).
 // Linux ABI:   No register preserved across function calls
 //              XMM0-XMM7 might hold parameters
 // Windows ABI: XMM6-XMM15 preserved across function calls
 //              XMM0-XMM3 might hold parameters
