This change prints out the segment information in the raw profile in
YAML format for testing. Since we don't capture build ids yet, we print
out <None> for now.

Update the YAML format print out of the profile to include a summary
instead of displaying the headers in the raw file buffer. This allows us
to release the raw buffer early saving memory.

Extend the Frame struct to hold the symbol name if requested
when a RawMemProfReader object is constructed. This change updates the
tests and removes the need to pass --debug to obtain the mapping from
GUID to symbol names.

To ease profile annotation, each of the callsites in a function can be
annotated with profile data - "IR metadata format for MemProf" [1]. This
patch extends the on-disk serialized record format to store the debug
information for allocation callsites incl inline frames. This change is
incompatible with the existing format i.e. indexed profiles must be
regenerated, raw profiles are unaffected.

This patch filters out callstack frames which can't be symbolized or if
the frames belong to the runtime. Symbolization may not be possible if
debug information is unavailable or if the addresses are from a shared
library. For now we only support optimization of the main binary which
is statically linked to the compiler runtime.

Use the macro based format to add a wrapper around the MemInfoBlock
when stored in the MemProfRecord. This wrapped block can then be
serialized/deserialized based on a schema specified by a list of enums.

Reapply https://reviews.llvm.org/D116784 now that
https://reviews.llvm.org/D118413 has landed with a couple of fixes:
* fix raw profile reader unaligned access identified by ubsan
* fix windows build by using MOCK_CONST_METHOD3 instead of MOCK_METHOD.
This change extends the RawMemProfReader to read all the sections of the
raw profile and symbolize the virtual addresses recorded as part of the
callstack for each allocation. For now the symbolization is used to
display the contents of the profile with llvm-profdata.

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.

The memprof profile reader tests rely on binary data which is generated
from and meant to be interpreted on little endian architectures. Add a
REQUIRES: x86_64-linux clause to both tests to ensure they don't fail on big
endian targets such as ppc.
This commit adds initial support to llvm-profdata to read and print
summaries of raw memprof profiles.
Summary of changes:
* Refactor shared defs to MemProfData.inc
* Extend show_main to display memprof profile summaries.
* Add a simple raw memprof profile reader.
* Add a couple of tests to tools/llvm-profdata.
