[clang][IFS][test][NFC] Tightening up clang-ifs tests to use -cc1 more often. Unless the test is explicitly testing a driver feature if clang interface stubs I have changed the tests to use %clang_cc1. This should make some changes I plan to make to the driver job pipeline cause fewer test changes and breakages.

[clang][IFS] Updating tests to pass on -fvisibility=hidden builds (NFCi). Special thanks to JamesNagurne who got to the bottom of this; landing this on his behalf. Differential Revision: https://reviews.llvm.org/D68897 llvm-svn: 374632

[clang][ifs] Clang Interface Stubs ToolChain plumbing. Second Landing Attempt: This patch enables end to end support for generating ELF interface stubs directly from clang. Now the following: clang -emit-interface-stubs -o libfoo.so a.cpp b.cpp c.cpp will product an ELF binary with visible symbols populated. Visibility attributes and -fvisibility can be used to control what gets populated. * Adding ToolChain support for clang Driver IFS Merge Phase * Implementing a default InterfaceStubs Merge clang Tool, used by ToolChain * Adds support for the clang Driver to involve llvm-ifs on ifs files. * Adds -emit-merged-ifs flag, to tell llvm-ifs to emit a merged ifs text file instead of the final object format (normally ELF) Differential Revision: https://reviews.llvm.org/D63978 llvm-svn: 374061

[clang][IFS][test] Fixing lit test breakages on macOS due to r374798 Adding the quotes breaks tests because on Darwin the name mangling is prefixed with an underscore. llvm-svn: 374805
