Adam Nemet 4208630cb7 Rename option to -lto-pass-remarks-output 
The new option -pass-remarks-output broke LLVM_LINK_LLVM_DYLIB because
of the duplicate option name with opt.

Adam Nemet 8fb7aa0930 [LTO] Add option to generate optimization records 
It is used to drive this from the clang driver via -mllvm.

Same option name is used as in opt.

Teresa Johnson a547919737 Split Bitcode/ReaderWriter.h into separate reader and writer headers 
Summary:
Split ReaderWriter.h which contains the APIs into both the BitReader and
BitWriter libraries into BitcodeReader.h and BitcodeWriter.h.

This is to address Chandler's concern about sharing the same API header
between multiple libraries (BitReader and BitWriter). That concern is
why we create a single bitcode library in our downstream build of clang,
which led to r286297 being reverted as it added a dependency that
created a cycle only when there is a single bitcode library (not two as
in upstream).

Peter Collingbourne d84bb1caf8 LTO: Use the correct mangler function in LTOCodeGenerator::applyScopeRestrictions(). 
We need to use the overload of Mangler::getNameWithPrefix that takes a
GlobalValue in order to mangle in the stdcall stack byte count for Windows
targets.

Davide Italiano e93d6b14f7 [UpdateCompilerUsed] API rename and cleanup, suggested by Rafaael. 
* UpdateCompilerUsed() -> updateCompilerUsed()
* ThinLTO doesn't use the API so we can remove the include
* Clean up unused #include <functional> from the header
* Rename #ifdef guard comment to be correct.
