Subject: When performing subframework header lookup, don't search for
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=efda0e8705e79a4b7de9f18b0d4618515f9e4bcc;p=clang

When performing subframework header lookup, don't search for
".framework/" in the path name, because it could be ".framework\" on
Windows. This whole function needs to be rewritten with PathV2.
