This patch adds the 'Zfa' extension for riscv, which is based on:

Dear all,
the fix for PR108527 came with a testcase that revealed a latent
bug with array sections and invalid array declarations. The ICE
first popped up on powerpc64-linux-gnu (big endian), but the issue
was not so clear as such on x86_64-pc-linux-gnu, as it did not show
up e.g. in valgrind.

We can reset SCEV after we fold, then SCEVs cache shouldn't have
anything in it when we go to remove ssa-names in remove_unreachable().
We were resetting it later sometimes if we were processing the array
bounds warning, so I removed that call and just always reset it now.

OK, thanks.
This patch introduces an instruction pattern for conditional shift

Tested on GCN3 Fiji gfx803.

Hi, this patch is present for GCC 14 since I understand it's not appropriate
to land it in GCC 13.
NUM_FIXED_BLOCKS = 2 since GCC define each function has aleast 2 blocks
one is entry block, the other is exit block.
So according this code, the function will not do cprop

With this patch a scheduling barrier is created to prevent the insn

stack to be swapped. Otherwise broken CFI information would be

is not currently declared as
