The ContainingSegment variable is only used to check whether we found
the address at this time. When building without Asserts this emits a
warning. So for now wrap this code in LLVM_DEBUG to avoid the warning.
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.

Print out the profile summary in YAML format to make it easier to for
tools and tests to read in the contents of the raw profile.

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.
