[SampleFDO] Add compression support for any section in ExtBinary profile format Previously ExtBinary profile format only supports compression using zlib for profile symbol list. In this patch, we extend the compression support to any section. User can select some or all of the sections to compress. In an experiment, for a 45M profile in ExtBinary format, compressing name table reduced its size to 24M, and compressing all the sections reduced its size to 11M.

REQUIRES: zlib
# Round trip from text --> compressed extbinary --> text
RUN: llvm-profdata merge --sample --extbinary -compress-all-sections -output=%t.1.profdata %S/Inputs/sample-profile.proftext
RUN: llvm-profdata merge --sample --text -output=%t.1.proftext %t.1.profdata
Add more diff -b to roundtrip-compress.test It was missing on the first test invocation. The flag is necessary to ignore line-ending differences on Windows.

Use diff -b on zlib tests so they pass on Windows Reviewers: hubert.reinterpretcast Subscribers: llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D71036
