gcc-5 affected in xenial and bionic.

gcc-6 affected in bionic only.

gcc-7 and gcc-8 affected, and currently have inflight SRU updates to
v7.5 and v8.3 in bionic, thus are not going to be updated at the moment
anywhere I don't think.

gcc-9 is fixed in focal.

Bug description:
  Miscompilation in autovectorized code.
   
  ---Steps to Reproduce---
   See GCC BZ: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92950

  The following testcase abort when being compiled with -O3 -march=z13
  on IBM Z:

  struct a {
    int b;
    char c;
  };
  struct a d = {1, 16};
  struct a *e = &d;

  int f = 0;

  int main() {
    struct a g = {0, 0 };
    f = 0;

    for (; f <= 1; f++) {
      g = d;
      *e = g;
    }

    if (d.c != 16)
      __builtin_abort();
  }

  The movv1qi pattern emits halfword load instructions instead of character
  loads.

  All GCC versions since GCC 5 are affected.
  Patches for GCC 8, 9, and 10 have been committed to the gcc.gnu.org branches.
   
  Userspace tool common name: gcc  
  The userspace tool has the following bit modes: 64 
  Userspace rpm: various Ubuntu gcc packages

  
  Package need to updated within LP
