When absolute paths that needed to be substituted by PathSanitizingFileCheck contained characters that could be part of regexp syntax, substitution didn't actually take place.
For example, substitution like
BUILD_DIR='/Users/johnsmith/swift-source/Ninja-RelWithDebInfoAssert+swift-DebugAssert'
didn't result in anything because of the '+' in the path, which caused the test suite to fail.This is an attempt to fix it.
This commit also adds the
--dry-run
flag to PathSanitizingFileCheck which was used to detect and debug this issue, but why not let it stay.cc @drodriguez @compnerd
