Implement full GCC-style extended inline assembly for ARM64 backend: - Add constraint parsing (constraint_priority, skip_constraint_modifiers) - Implement register allocation (asm_compute_constraints) - Add code generation for prolog/epilog and load/store (asm_gen_code) - Support output/input/read-write operands with r, w, f, x, m, g constraints - Support immediate constraints (i, I, J, K, L, n) - Handle clobber lists (registers, memory, cc) - Support constraint references, early clobber, named operands - Fix '#' character handling in tccpp.c for ARM64 asm mode Tests: Add comprehensive test suite with 18 test cases covering all features. All existing TCC tests continue to pass.
