9def83c6d0 [memprof] Refactor out the MemInfoBlock into a macro based def.
This patch refactors out the MemInfoBlock definition into a macro based
header which can be included to generate enums, structus and code for
each field recorded by the memprof profiling runtime.

8306968b59 [memprof] Move the meminfo block struct to MemProfData.inc.
The definition of the MemInfoBlock is shared between the memprof
compiler-rt runtime and llvm/lib/ProfileData/. This change removes the
memprof_meminfoblock header and moves the struct to the shared include
file. To enable this sharing, the Print method is moved to the
memprof_allocator (the only place it is used) and the remaining uses are
updated to refer to the MemInfoBlock defined in the MemProfData.inc
file.

Also a couple of other minor changes which improve usability of the
types in MemProfData.inc.
* Update the PACKED macro to handle commas.
* Add constructors and equality operators.
* Don't initialize the buildid field.

3a4d373ec2 [memprof] Align each rawprofile section to 8b.
The first 8b of each raw profile section need to be aligned to 8b since
the first item in each section is a u64 count of the number of items in
the section.
Summary of changes:
* Assert alignment when reading counts.
* Update test to check alignment, relax some size checks to allow padding.
* Update raw binary inputs for llvm-profdata tests.

a2ce97cc3f [memprof] Fix unit test build after refactoring shared header.
The memprof unittest also needs to include the MemProfData.inc header
directly to have access to MEMPROF_RAW_MAGIC and MEMPROF_RAW_VERSION
globals.

545866cb05 [memprof] Add a raw binary format to serialize memprof profiles.
This change implements the raw binary format discussed in
https://lists.llvm.org/pipermail/llvm-dev/2021-September/153007.html

Summary of changes
* Add a new memprof option to choose binary or text (default) format.
* Add a rawprofile library which serializes the MIB map to profile.
* Add a unit test for rawprofile.
* Mark sanitizer procmaps methods as virtual to be able to mock them.
* Extend memprof_profile_dump regression test.
