[PATCH v2 0/8] ARM AArch64 Support for BSD

[Ajeet Singh <itachis6234@gmail.com>]

Patch 1: Previous patches 1 to 5, which were reviewed and acked, have been folded into this patch.Some changes that were suggested,
         such as replacing "pstate &= ~PSTATE_C" with faster constructs like "env->CF = 0", have been addressed in patch 8.
Patch 2: In this patch, patches 6 to 11 have been folded. Changes such as using "ROUND_DOWN" for stack pointer calculation
         and replacing "__uint128_t" with "Int128" in the following patch 8 have been addressed. Also, "CPUARMState" will be
         changed to "CPUArchState" in the upcoming version, and the issue with "-R" is being worked on separately.
Patch 3: Patches 12 to 16 were reviewed and folded. The function "get_second_rval" will be used upstream.
Patch 4: Patches 17 to 19 were folded, and "__uint128_t" to "Int128" has been fixed in patch 8. Also, the suggestion to
         use "const_le32()" has been deferred for now.
Patch 5: Previously patch 20, the FP suggestion is being deferred, but the patch is ready for review.
Patch 6: Previously patch 21 has been reviewed.
Patch 7: Previously patch 22, same as patch 5.
Patch 8: Previously patch 23. For now, no changes, but issues of other patches have been addressed, such as updating
         AArch64 code to use CF directly and changing FP data structures to use Int128 instead of __uint128_t.
