40. Fix two clang compiler warnings in pcre2test when only one code unit width
is supported.
41. Upgrade RunTest to automatically re-run test 2 with a large (64M) stack if
it fails when running the interpreter with a 16M stack (and if changing the
stack size via pcre2test is possible). This avoids having to manually set a
large stack size when testing with clang.
