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 unit tests use an older version of gmock (included in the
repo) which does not build cleanly with -pedantic:
https://github.com/google/googletest/issues/2650
For now just silence the warning by disabling pedantic and add the
appropriate flags for gcc and clang.
MemProfUnitTest now depends on libcxx but the dependency is not
explicitly expressed in build system, causing build races. This patch
addresses this issue.
