This reverts r369486 (git commit 8d18384809957cc923752e10a86adab129e3df48)

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.

ff88899fb1 [opt-viewer] Make filter_=None by default in get_remarks and gather_results
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.

1973dbeae9 [opt-viewer] Add javascript to expand/hide full message for multiline remarks.
This patch adds support for displaying remarks with multiple
lines. For such remarks, it creates a hidden div
containing the message's lines except the first one in a <pre>
tag. It also prepends a link (with '+' as text) to the regular remark
line. This link can be used to show/hide the div containing the
full remark.

In combination with D57159, this allows for better displaying of
multiline remarks in the html pages generated by opt-viewer.

The Javascript is very simple and should be supported by any recent
major browser.

3384da9f27 [opt-viewer] Don't Decode HTML bytes for Python 2
Summary:
D36624 added some python3 compatibility. But that fix has a problem..

With python2 (which is specified by `#!/usr/bin/env python2.7`), if the env variables do not specify the UTF8,
and the source file is UTF8 (contains non-ASCII symbols), then the `.decode('utf-8')` causes the following exception:
```
Reading YAML files...
Rendering HTML files...

    </tr>'''.format(**locals()), file=self.stream)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf4' in position 47: ordinal not in range(128)
```
This is similar to https://bugs.llvm.org/show_bug.cgi?id=33548, which was fixed by https://reviews.llvm.org/D37661

Unlike that fix, here, *removing* `.decode('utf-8')` actually fixes it.

Since i assume that the original fix is needed, i simply made
that fix conditional, since for python2 it actually breaks things.

f4edf082e8 [opt-viewer] Listify dict_items for Py3 indexing
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()`.

81032e2009 [opt-viewer] Reduce memory consumption by another 20-25%
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 |

961ab77c75 [opt-viewer] Reduce memory consumption
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.

  | # of files            |   60 |  114 |  308 |  605 | 1370 |

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.

external tools.

The tools are installed under <install>/share/opt-viewer/.
