Reapply r207477 and r207479 without cyclic dependency Fixed by moving ProcessWarningOptions from Frontend into Basic. All of the dependencies for ProcessWarningOptions were already in Basic, so this was a small change. llvm-svn: 207549

[modules] Simplify -cc1 interface for enabling implicit module maps. We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789

// RUN: %clang_cc1 -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -fdisable-module-hash \
test: Disable standard system includes in %clang_cc1 This adds -nostdsysteminc to the %clang_cc1 expansion, which should make it harder to accidentally write tests that depend on headers in /usr/include. It also updates a few tests that use -isysroot <x> and a darwin triple to omit the triple and use -isystem <x>/usr/include instead, making them a little bit more general. Incidentally, this fixes a test failure I'm seeing on darwin in Modules/stddef.c, that happens because my system finds a stddef.h in /usr/include. llvm-svn: 219030
