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
A number of test cases assume that an "int" parameter or return value will be represented in the IR as a plain "i32" type. This causes the tests to spuriously fail on platforms where int is not a 32-bit type, or where the ABI requires attributes like "signext" or "zeroext" to be used. This patch adds -triple or -target parameters to force those tests to use the i386-unknown-unknown target. llvm-svn: 166551

Initial support for code generation from .ast files. - Doesn't actually work yet because only module level asm's get correctly marked as externally visible in the PCH. - Other things like 'clang-cc foo.ast -ast-dump' now work, as well. llvm-svn: 82107

// CHECK: module asm "foo"
__asm__("foo");
Switch ProcessASTInputFile to still use ParseAST. - Currently this requires us to fake an input file. - This allows Sema to be keep all the logic for how to pull decls out of the external AST source and how to handle things like tentative definitions. llvm-svn: 82432
