Revert "Revert r241620 and follow-up commits" and move the initialization of the llvm targets from clang/CodeGen into ClangCheck.cpp and CIndex.cpp. llvm-svn: 241653

// REQUIRES: x86-registered-target
When writing a PCH file, keep track of all of the non-static, non-inline external definitions (and tentative definitions) that are found at the top level. The corresponding declarations are stored in a record in the PCH file, so that they can be provided to the ASTConsumer (via HandleTopLevelDecl) when the PCH file is read. llvm-svn: 69005

// Test with pch.
Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446

Eliminate &&s in tests. - 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious. llvm-svn: 86430

// RUN: grep "@x = common global i32 0" %t | count 1
Replace 'grep foo | count 0' with 'not grep foo'. This avoids depending on pipefail not being used. llvm-svn: 185648

// RUN: not grep "@z" %t
When building a PCH file, don't perform end-of-translation-unit wrap-up (e.g., turning tentative definitions into definitions). Also, very that, when we actually use the PCH file, we get the ride code generation for tentative definitions and definitions that show up in the PCH file. llvm-svn: 69043
