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.

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 |
| total file size (MB) | 22 | 51 | 219 | 202 | 1034 |
|------------------------+------+------+------+------+------|
| Avg remark size before | 4339 | 4792 | 4761 | 4096 | 4607 |
| Avg remark size after | 3446 | 3641 | 3567 | 3146 | 3347 |
| Rate | 0.79 | 0.76 | 0.75 | 0.77 | 0.73 |

This allows to pass the build directory where all the opt.yaml files are
rather than find | xargs which may invoke opt-viewer multiple times producing
incomplete html output.
The patch generalizes the same functionality from opt-diff.

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.
