Rename XOR* mnemonics to EOR*

Summary: TCA mnemonics all start with an X, XOR was the only exception. This renaming makes it so that only TCA mnemonics start by an X. On KV3-1 and KV3-2, we install synthetics so that XOR still works. However, the KV4-1 will not expose a XOR mnemonic. libgloss/ChangeLog: 2023-10-31 Paul Iannetta <[email protected]> * kvx-elf/include/kvx/asm_context.h newlib/ChangeLog: 2023-10-31 Paul Iannetta <[email protected]> * libc/machine/kvx/memcmp.S: Rename XOR* mnemonics to EOR*.
