  LoongArch V1.1 release is out at
https://www.loongson.cn/uploads/images/2023102309132647981.%E9%BE%99%E8%8A%AF%E6%9E%B6%E6%9E%84%E5%8F%82%E8%80%83%E6%89%8B%E5%86%8C%E5%8D%B7%E4%B8%80_r1p10.pdf.

It brings the following new instructions:

- atomic cas: amcas{_db}.b/h/w/d
- ll-sc: sc.q, llacq.w/d, screl.w/d
- estimated reciprocal: frecipe/frsqrte and their vector counterpart

Support and tests for these new instructions are added.

Changes since v1:

- Add support for "sc.q r4, r5, r6, 0" and "llacq.w/d / screl.w/d r4,
  r5, 0"

Ping.  Now we are very close to the end of GCC 14 stage 1 and we need
Binutils support for adding LA664 features into GCC.

I guess the manual will be released on Nov 28, but GCC 14 stage 1 ends
on Nov 19.

Does the mnemonics in this series look OK to you?  If yes then I can
start to use them in GCC (and a document change for minimal GAS version
required by -mxxx options can be added in Stage 3 or 4).

Yeah, it look OK to me.
