  -----------
  [UBSan] Support src:*=sanitize for multiple ignorelists. (#141640)

See: https://github.com/llvm/llvm-project/issues/139128 and
https://github.com/llvm/llvm-project/pull/140529 for the background.

The introduction of these new tests (ubsan-src-ignorelist-category.test)
`-fsanitize-ignorelist=%t/src.ignorelist
-fsanitize-ignorelist=%t/src.ignorelist.contradict9` in this PR will not
lead to failures in the previous implementation (without this PR). This
is because the existing logic distinguishes between Sections in
different ignorelists, even if their names are identical. The order of
these Sections is preserved using a `vector`.
