Justin Bogner 9e9a057a9b InstrProf: Support for value profiling in the indexed profile format
Add support to the indexed instrprof reader and writer for the format
that will be used for value profiling.

Patch by Betul Buyukkurt, with minor modifications.

Alexander Kornienko f00654e31b Revert r240137 (Fixed/added namespace ending comments using clang-tidy. NFC)
Apparently, the style needs to be agreed upon first.

Chandler Carruth d9903888d9 [cleanup] Re-sort all the #include lines in LLVM using
utils/sort_includes.py.

I clearly haven't done this in a while, so more changed than usual. This
even uncovered a missing include from the InstrProf library that I've
added. No functionality changed here, just mechanical cleanup of the
include order.

Benjamin Kramer a7c40ef022 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

Justin Bogner 821d7471f9 InstrProf: Allow multiple functions with the same name
This updates the instrumentation based profiling format so that when
we have multiple functions with the same name (but different function
hashes) we keep all of them instead of rejecting the later ones.

There are a number of scenarios where this can come up where it's more
useful to keep multiple function profiles:

* Name collisions in unrelated libraries that are profiled together.
* Multiple "main" functions from multiple tools built against a common
  library.
* Combining profiles from different build configurations (ie, asserts
  and no-asserts)

The profile format now stores the number of counters between the hash
and the counts themselves, so that multiple sets of counts can be
stored. Since this is backwards incompatible, I've bumped the format
version and added some trivial logic to skip this when reading the old
format.

Justin Bogner b7aa26303b ProfileData: Add support for the indexed instrprof format
This adds support for an indexed instrumentation based profiling
format, which is just a small header and an on disk hash table.  This
format will be used by clang's -fprofile-instr-use= for PGO.
