Duncan P. N. Exon Smith 4543aac96e PGO: Indicate errors in profile runtime API
Return 0 for success, non-0 for failure.

Duncan P. N. Exon Smith e5edc8869b PGO: Substitute pid for %p in filename
Add logic to do a printf-style substitution of %p for the process pid in
the filename.

It's getting increasingly awkward to work on lib/profile without test
infrastructure.  This needs to be fixed!

Duncan P. N. Exon Smith 9edbae0f16 PGO: Change runtime prefix from pgo to profile
These functions are in the profile runtime.  PGO comes later.

Unfortunately, there's only room for 16 characters in a Darwin section,
so use __llvm_prf_ instead of __llvm_profile_ for section names.

Duncan P. N. Exon Smith 54cc0e2d81 PGO: Update interface for writing instrumentation data to file
__llvm_pgo_write_default_file() was a bad name, since it checked the
environment (it wasn't just a default file).

  - Change __llvm_pgo_write_file() to __llvm_pgo_write_file_with_name()
    and make it static.

  - Rename __llvm_pgo_write_default_file() to __llvm_pgo_write_file().

  - Add __llvm_pgo_set_filename(), which sets the filename for
    subsequent calls to __llvm_pgo_write_file().

Duncan P. N. Exon Smith 775c178a90 PGO: Add explicit static initialization
Instead of relying on explicit static initialization from translation
units, create a new file, InstrProfilingRuntime.cc, with an
__llvm_pgo_runtime variable.  After this commit (and its pair in clang),
the driver will create a use of this variable.  Unless the user defines
their own version, the new object file will get pulled in, including
that C++ static initialization that calls
__llvm_pgo_register_write_atexit.

The result is that, at least on Darwin, static initialization typically
consists of a single function call, which registers a writeout functino
atexit.  Furthermore, users can skip even this behaviour by defining
their own __llvm_pgo_runtime.

Duncan P. N. Exon Smith da0de8a237 PGO: Split out initialization of section bounds
Currently we register instrumentation data at runtime to determine the
bounds of the sections where the data lives.  Soon we'll implement
platform-specific linker magic to determine this at link time.

Move this logic to a separate file, so that our build system can choose
the correct platform-specific code.

No functionality change intended.

Duncan P. N. Exon Smith 8353a26e85 PGO: Splitting implementation files; no functionality change
Split implementation files along a uses-libc/shouldn't-use-libc
boundary.

  - InstrProfiling.h is a shared header.

  - InstrProfiling.c provides an API to extract profiling data from the
    runtime, but avoids the use of libc.  Currently this is a lie:
    __llvm_pgo_write_buffer() uses `FILE*` and related functions.  It
    will be updated soon to write to a `char*` buffer instead.

  - InstrProfilingExtras.c provides a more convenient API for
    interfacing with the profiling runtime, but has logic that does (and
    will continue to) use libc.

Duncan P. N. Exon Smith 77a88e3064 PGO: Statically generate data structures
In instrumentation-based profiling, we need a set of data structures to
represent the counters.  Previously, these were built up during static
initialization.  Now, they're shoved into a specially-named section so
that they show up as an array.

As a consequence of the reorganizing symbols, instrumentation data
structures for linkonce functions are now correctly coalesced.

This is the first step in a larger project to minimize runtime overhead
and dependencies in instrumentation-based profilng.  The larger picture
includes removing all initialization overhead and making the dependency
on libc optional.

Make behavior introduced in r202820 conditional (under legacy_pthread_cond flag).
The new issue that we've hit with the satellite pthread_cond_t struct is
that pthread_condattr_getpshared does not work (satellite data is not shared between processes).
The idea is that most processes do not use pthread 2.2.5.
The rare ones that use (2.2.5 is dated by 2002) must specify legacy_pthread_cond=1
on their own risk.
