This should make sure that most new uses use the std prefix.

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.

FIXME: line_iterator should be tolerant of CR.

This isn't a format we'll want to write out in practice, but moving it
to the writer library simplifies llvm-profdata and isolates it from
further changes to the format.
This also allows us to update the tests to not rely on the text output
format.

The `llvm-profdata show` command summarizes a profdata file's contents
in a human readable format.

This introduces the ProfileData library and updates llvm-profdata to
use this library for reading profiles. InstrProfReader is an abstract
base class that will be subclassed for both the raw instrprof data
from compiler-rt and the efficient instrprof format that will be used
for PGO.

We'll be adding a few more subcommands in the near future.

This also uses line_iterator to simplify the parsing logic.

Chandler voiced some concern with checking this in without some
discussion first. Reverting for now.
This reverts r203703, r203704, r203708, and 203709.

This was leftover from an approach I abandoned, but I forgot to update
it before committing.

This replaces the llvm-profdata tool with a version that uses the
recently introduced Profile library. The new tool has the ability to
generate and summarize profdata files as well as merging them.

This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.

After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

This will make it easier to switch the default to being binary files.

Introducing llvm-profdata, a tool for merging profile data generated by
PGO instrumentation in clang.
- The name indicates a file extension of <name>.profdata. Eventually
profile data output by clang should be changed to that extension.
- llvm-profdata merges two profiles. However, the name is more general,
since it will likely pick up more tasks (such as summarizing a single
profile).
- llvm-profdata parses the current text-based format, but will be
updated once we settle on a binary format.
