Brendan Punsky 7b588d0818 rexcode/arm64: implement CCMP/CCMN register-form encode forms
First entries of the encode-coverage effort. Adds CCMP_REG/CCMN_REG (W/X) to ENCODING_TABLE with llvm-mc-verified bit patterns; the table metaprogram regenerates the encode/decode blobs and the typed builders auto-generate (inst_ccmp_reg/inst_ccmn_reg).

Verified: encode matches llvm-mc (CCMP X1,X2,#3,EQ=0xFA420023; CCMN W5,W6,#7,NE=0x3A4610A7), decode round-trips, arm64 check+tests pass. Needs no encoder change (reuses RN/RM/NZCV_FIELD/COND_HI). The imm5 forms (immediate at bits 20:16) need a new Operand_Encoding and follow separately.

Workflow proven: llvm-mc as the encoding oracle -> SoT entry -> regen -> builder auto-generates -> verify.

The Odin Programming Language

Odin is a general-purpose programming language with distinct typing, built for high performance, modern systems, and built-in data-oriented data types. The Odin Programming Language, the C alternative for the joy of programming.

package main

import "core:fmt"

main :: proc() {
	program := "+ + * 😃 - /"
	accumulator := 0

	for token in program {
		switch token {
		case '+': accumulator += 1
		case '-': accumulator -= 1
		case '*': accumulator *= 2
		case '/': accumulator /= 2
		case '😃': accumulator *= accumulator
		case: // Ignore everything else
		}
	}

	fmt.printf("The program \"%s\" calculates the value %d\n",
	           program, accumulator)
