Correct handling of variable offset minus constant in -Warray-bounds

Hi Martin,
I see these failing on aarch64-linux-gnu as well:
FAIL: gcc.dg/Wstringop-overflow-47.c pr97027 (test for warnings, line 34)
FAIL: gcc.dg/Wstringop-overflow-47.c pr97027 (test for warnings, line 37)
FAIL: gcc.dg/Wstringop-overflow-47.c pr97027 (test for warnings, line 42)
Thanks. It looks like I removed the xfails a little bit too
indiscriminately. The test passes with an x84_64 compiler but
the aarch64 IL still isn't handled. Let me take care of that.
FWIW, I don’t see these on aarch64-linux-gnu:
Good! :) I fixed these problems just yesterday.
Martin
