[llvm-rc] Look for "clang-<major>" when locating a suitable preprocessor
In some cases, there's no adjacent executable named "clang" or
"clang-cl", but one name "clang-<major>". This logic doesn't
cover every possible deployment setup of course, but should
cover more fairly common/reasonable cases.

for discussion about a case where this would have been helpful.
