re PR ipa/63196 (FAIL: g++.dg/torture/pr57140.C -O3 -fomit-frame-pointer (internal compiler error))

PR ipa/63196
* tree-inline.c (copy_loops): The source loop header should

(tree_function_versioning): If loops need fixup after removing
unreachable blocks fix them.
* omp-low.c (simd_clone_adjust): Do not add incr block to
loop under construction.
