Introduce -fembed-bitcode driver option Summary: This is the clang driver part of the change to embedded bitcode. This includes: 1. -fembed-bitcode option which breaks down the compilation into two stages. The first stage emits optimized bitcode and the second stage compiles bitcode into object file. 2. -fembed-bitcode-marker option which doesn't really break down to two stages to speedup the compilation flow. 3. pass the correct linker flag to darwin linker if tool chains supports embedded bitcode.

Embed bitcode in object file (clang cc1 part) Summary: Teach clang to embed bitcode inside bitcode. When -fembed-bitcode cc1 option is used, clang will embed both the input bitcode and cc1 commandline into the bitcode in special sections before compiling to the object file. Using -fembed-bitcode-marker will only introduce a marker in both sections.

[Driver] Fix the case when use -fembed-bitcode and -flto= together Summary: -fembed-bitcode was only checking for old style LTO flag (-flto) but not considering the new -flto= style option. That makes clang output bitcode embedded in bitcode object when using -flto= and -fembed-bitcode= together. Now clang should output normal bitcode file when using LTO and ignores -fembed-bitcode option.
