mark build::cfg::start_new_block as inline(never)
LLVM has a bug - PR32488 - where it fails to deduplicate allocas in some circumstances. The function `start_new_block` has allocas totalling 1216 bytes, and when LLVM inlines several copies of that function into the recursive function `expr::into`, that function's stack space usage goes into tens of kiBs, causing stack overflows. Mark `start_new_block` as inline(never) to keep it from being inlined, getting stack usage under control. Fixes #40493. Fixes #40573.
