Fixes #10994 CASE and BCASE were used by 7c in switch statements, cmd/compile does not use them, cmd/assemble couldn't assemble them, and the arm64 peephole optimiser didn't know about them.

The old numerical names like 6.out.go are a relic from the old tools. Easier to rename than explain. The anames.go files were modified by go generate; no changes beyond the explanatory comment at the top.

ARM64 (ARMv8) has 32 general purpose, 64-bit integer registers (R0-R31), 32 64-bit scalar floating point registers (F0-F31), and 32 128-bit vector registers (unused, V0-V31). R31 is either the stack pointer (RSP), or the zero register (ZR), depending on the instruction. Note the distinction between the hardware stack pointer, RSP, and the virtual stack pointer SP. The (hardware) stack pointer must be 16-byte aligned at all times; the RSP register itself must be aligned, offset(RSP) only has to have natural alignment. Instructions are fixed-width, and are 32-bit wide. ARM64 supports ARMv7 too (32-bit ARM), but not in the same process. In general, there is not much in common between 32-bit ARM and ARM64, it's a new architecture. All implementations have floating point instructions. This change adds a Prog.To3 field analogous to Prog.To. It is used by exclusive load/store instructions such as STLXR which read from one register, and write to both a register and a memory address. STLXRW R1, (R0), R3 This will store the word contained in R1 to the memory address pointed by R0. R3 will be updated with the status result of the store. It is used to implement atomic operations. No other changes are made to the portable Prog and Addr structures. Change-Id: Ie839029aa5265bbad35769d9689eca11e1c48c47 Reviewed-on: https://go-review.googlesource.com/7046Reviewed-by:
