[RFC] Don't move cold code out of loop by checking bb count

There was a patch trying to avoid move cold block out of loop: https://gcc.gnu.org/pipermail/gcc/2014-November/215551.html Richard suggested to "never hoist anything from a bb with lower execution frequency to a bb with higher one in LIM invariantness_dom_walker before_dom_children". This patch

[PATCH] Support cond_add/sub/mul/div for vector float/double.

Hi: This patch supports cond_add/sub/mul/div expanders for vector float/double. There're still cond_fma/fms/fnms/fma/max/min/xor/ior/and left which I failed to figure out a testcase to validate them. Also cond_add/sub/mul for vector integer. Bootstrap is ok, survive the regression test

[PATCH] Fix ICE when mixing VLAs and statement expressions [PR91038]

Here is an attempt to fix some old and annoying bugs related to VLAs and statement expressions. In particulary, this seems to fix the issues with variably-modified types which are returned from statement expressions (which works on clang), but there are still bugs remaining related to structs
