Snehasish Kumar 61c75eb637 [memprof] Initialize MemInfoBlock data.
This patch updates the existing default no-arg constructor for
MemInfoBlock to explicitly initialize all members. Also add missing
DataTypeId initialization to the other constructor. These issues were
exposed by msan on patch D121179. With this patch D121179 builds cleanly
on msan.

Snehasish Kumar de54e4ab78 Reland "[memprof] Extend the index prof format to include memory profiles."
This reverts commit 0f73fb18ca.

Use llvm/Profile/MIBEntryDef.inc instead of relative path.

Generated the raw profile data with `-mllvm
-enable-name-compression=false` so that builbots where the reader is
built without zlib do not fail.

Also updated the test build instructions.

Snehasish Kumar 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.

Snehasish Kumar 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.
