Switch these two tests to use the Clang driver instead of CC1. They want to do "realistic" includes, and so need the header search logic now in the driver. This in turn requires switching the CC1 options to the actual driver options, and passing -Xclang where there is no analogy. llvm-svn: 143805

lib/Frontend/InitHeaderSearch.cpp: Tweak AddPath() to accept "/foo/bar" (not "X:\foo\bar") with -isysroot. test/PCH/reloc.c can pass. FIXME: We should consider better isysroot scheme on Win32 hosts. llvm-svn: 130683

Introduce the notion of "Relocatable" precompiled headers, which are built with a particular system root directory and can be used with a different system root directory when the headers it depends on have been installed. Relocatable precompiled headers rewrite the file names of the headers used when generating the PCH file into the corresponding file names of the headers available when using the PCH file. Addresses <rdar://problem/7001604>. llvm-svn: 74885
