This patch is a prerequisite for using LangStandard from Driver in https://reviews.llvm.org/D64793. It moves LangStandard* and InputKind::Language to Basic. It is mostly mechanical, with only a few changes of note: - enum Language has been changed into enum class Language : uint8_t to avoid a clash between OpenCL in enum Language and OpenCL in enum LangFeatures and not to increase the size of class InputKind. - Now that getLangStandardForName, which is currently unused, also checks both canonical and alias names, I've introduced a helper getLangKind which factors out a code pattern already used 3 times. The patch has been tested on x86_64-pc-solaris2.11, sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu. There's a companion patch for lldb which uses LangStandard.h (https://reviews.llvm.org/D65717). While polly includes isl which in turn uses InputKind::C, that part of the code isn't even built inside the llvm tree. I've posted a patch to allow for both InputKind::C and Language::C upstream (https://groups.google.com/forum/#!topic/isl-development/6oEvNWOSQFE). Differential Revision: https://reviews.llvm.org/D65562 llvm-svn: 367864
