This reverts commit r266477.
This commit introduces cyclic dependency. This commit has "Analysis" depend on "ProfileData",
while "ProfileData" depends on "Object", which depends on "BitCode", which
depends on "Analysis".
llvm-svn: 266619
Adds an interface to get ProfileSummary for a module and makes InlineCost use ProfileSummary to get max function count.

llvm-svn: 266477
Summary:
Adds support for in-memory round-trip of sample profile data along with basic
round trip unit tests. This will also make it easier to include unit tests for
future changes to sample profiling.

Have the InstrProfWriter return a MemoryBuffer instead of a
std::string. This fixes the alignment issues the reader would hit, and
it's a more appropriate type for this anyway.
I've also removed an ugly helper function that's not needed since
we're allowing initializer lists now, and updated some error code
checks based on MSVC's issues with r229473.
This reverts r229483, reapplying r229478.
llvm-svn: 229602
This added API to the InstrProfWriter to write to a string so I could
write unittests without using temp files. This doesn't really work,
since the format has tighter alignment requirements than a char.
This reverts r229478 and its follow-up, r229481.
llvm-svn: 229483
This required some minor API to be added to these types to avoid
needing temp files.
Also, I've used initializer lists in the tests, as MSVC 2013 claims to
support them. I'll redo this without them if the bots complain.

The llvm-level tests for coverage mapping need a binary input file,
which means they're hard to understand, hard to update, and it's
difficult to add new ones. By adding some unit tests that build up the
coverage data structures in C++, we can write more meaningful and
targeted tests.
