[NFC] Fix for InterfaceStubs tests (adding REQUIRES: x86-registered-target). clang-hexagon-elf bot was failing with: 'No available targets are compatible with triple "x86_64-unknown-linux-gnu"' Adding a "// REQUIRES: x86-registered-target" to these tests to quiet the bot. llvm-svn: 363963

// REQUIRES: x86-registered-target
[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] Clang Interface Stubs, first version (second landing attempt). This change reverts r363649; effectively re-landing r363626. At this point clang::Index::CodegenNameGeneratorImpl has been refactored into clang::AST::ASTNameGenerator. This makes it so that the previous circular link dependency no longer exists, fixing the previous share lib (-DBUILD_SHARED_LIBS=ON) build issue which was the reason for r363649. Clang interface stubs (previously referred to as clang-ifsos) is a new frontend action in clang that allows the generation of stub files that contain mangled name info that can be used to produce a stub library. These stub libraries can be useful for breaking up build dependencies and controlling access to a library's internal symbols. Generation of these stubs can be invoked by: clang -fvisibility=<visibility> -emit-interface-stubs \ -interface-stub-version=<interface format> Notice that -fvisibility (along with use of visibility attributes) can be used to control what symbols get generated. Currently the interface format is experimental but there are a wide range of possibilities here. Currently clang-ifs produces .ifs files that can be thought of as analogous to object (.o) files, but just for the mangled symbol info. In a subsequent patch I intend to add support for merging the .ifs files into one .ifs/.ifso file that can be the input to something like llvm-elfabi to produce something like a .so file or .dll (but without any of the code, just symbols).
