[ThinLTO] Print module summary index to assembly Summary: Implements AsmWriter support for printing the module summary index to assembly with the format discussed in the RFC "LLVM Assembly format for ThinLTO Summary". Implements just enough of the parsing support to recognize and ignore the summary entries. As agreed in the RFC thread, this will be the behavior when assembling the IR. A follow on change will implement parsing/assembling of the summary entries for use by tools that currently build the summary index from bitcode.

[ThinLTO] Represent relative BF using a scaled representation . Summary: The current integer representation of relative block frequency prevents representing relative block frequencies below 1. This change uses a 8 of the 29 bits to represent the decimal part by using a fixed scale of -8.
