This reverts r369486 (git commit 8d18384809)
The opt-viewer tests don't pass after this change, and fixing them isn't
trivial. opt-viewer.py imports optmap, which requires adjusting
pythonpath, which is more work than I'm willing to do to fix forward.
llvm-svn: 370095
Summary:
Since these files depend on the built python modules, they need to use
the right python binary to run them. So use configure_file
to set the right shebang line.

WarnMissedTransforms.cpp produces remarks that use !Failure tags.
These weren't supported in optrecord.py, so if you encountered one in any of
the tools, the tool would crash.
Add them as a type of missed optimization.

Right now, if you try to use optdiff.py on any opt records, it will fail because
its calls to gather_results weren't updated to support filtering.
Since filters are supposed to be optional, this makes them None by default in
get_remarks and in gather_results. This allows other tools that don't support
filtering to still use the functions as is.

This allows limiting the displayed remarks to the ones with names
matching the filter (regular) expression.
Generating html pages for a larger project with optimization remarks can
result in a huge HTML documents and using --filter allows to focus on a
set of interesting remarks.

This is a Swift feature. The output stream for the index page and the source
HTML page is utf-8 now.
The next patch will add the HTML magic to properly render these characters in
the browser.

Most likely, this is not how we want to handle this in the long term. This
code should probably be in the Swift repo and somehow plugged into the
opt-viewer. This is still however very experimental at this point so I don't
want to over-engineer it at this point.

Detects whether we have the Python modules (pygments, yaml) required by
opt-viewer and hooks this up to REQUIRES.
This fixes https://bugs.llvm.org/show_bug.cgi?id=34129 (the lack of opt-viewer
testing).
It's also related to https://github.com/apple/swift/pull/12938 and the idea is
to expose LLVM_HAVE_OPT_VIEWER_MODULES to the Swift cmake.

Fixes since the first commit:
1. Disable syntax highlighting as different versions of pygments generate
different HTML
2. Use llvm-cxxfilt from the build

I've seen cases where tiny inlined functions have such a high execution count
that most everything would show up with a relative of hotness of 0%. Since
the inlined functions effectively disappear you need to tune in the lower
range, thus we need more precision.

This is slightly less verbose for the common case of a single build directory
and more intuitive when using this API directly from the interpreter.

Summary:
In Python 2, calling `dict.items()` returns an indexable `list`, whereas
on Python 3 it returns a set-like `dict_items` object, which cannot be
indexed. Explicitly onvert the `dict_items` object so that it can be
indexed when using Python 3.
In combination with D36622, D36623, and D36624, this change allows
`opt-viewer.py` to exit successfully when run with Python 3.4.
Test Plan:
Run `opt-viewer.py` using Python 3.4 and confirm it does not encounter a
runtime error when when indexing into `dict.items()`.

Summary:
In Python 2, `intern()` is a builtin function available to all programs.
In Python 3, it was moved into the `sys` module, available as
`sys.intern`. Import it such that, within `optrecord.py`, `intern()` is
available whether run using Python 2 or 3.
Test Plan:
Run `opt-viewer.py` using Python 3, confirm it no longer
encounters a runtime error when `intern()` is called.

The Args field of the remark which consists of a list of mappings in YAML is
translated into a list of (small) dicts on Python. An empty dict is 280 bytes
on my system so we can save memory by using a tuple of tuples instead.
Making a tuple of tuples rather than a list of tuples allows Args to be shared
with the key of the remark. This is actually an even greater saving. (Keys
are alive throughout the entire run in all_remarks.)
Here are a few opt-stats runs with different input sizes while measuring heap
usage with heapy. Avg remark size is simply estimated as
heap-size / # of remarks:
| # of files | 60 | 114 | 308 | 605 | 1370 |
| # of remarks | 20K | 37K | 146K | 180K | 640K |

The observation is that we have a lot of similar remarks with lots of
identical strings (e.g. file paths, text from the remark). Storing a copy of
each of those strings in memory is wasteful. This makes all the strings in
the remark interned which maintains a single immutable instance that is
referenced everywhere.
I get an average 20% heap size reduction with this but it's possible that this
varies with the typical length of the file paths used. (I used heapy to
report the heap size.) Runtime is same or a tiny bit better.

Summary:
When using opt-viewer.py with files with '#' in their name, such as
'foo#bar.cpp', opt-viewer.py would generate links such as
'/path/to/foo#bar.cpp.opt.yaml#L42'. In this case, the link is
interpreted by browsers as a link to the file '/path/to/foo', and to the
section within that file with ID 'bar.cpp.opt.yaml#L42'.
To work around this issue, replace '#' with '_' in file names and links
in opt-viewer.py.

We weren't installing opt-viewer and co before, this fixes the omission. I am
also moving the tools from utils/ to tools/. I believe that this is more
appropriate since these tools have matured greatly in the past year through
contributions by multiple people (thanks!) so they are ready to become
external tools.
The tools are installed under <install>/share/opt-viewer/.
I am *not* adding the llvm- prefix. If people feel strongly about adding
that, this is probably a good time since the new location will require some
mental adjustment anyway.
