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.

Summary:
Provide feedback to users of opt-diff.py, opt-stats.py, and opt-viewer.py,
on how many YAML files have finished being processed, and how many HTML
files have been generated. This feedback is particularly helpful for
opt-viewer.py, which may take a long time to complete when given many
large YAML files as input.
The progress indicators use simple output such as the following:
```
Reading YAML files...
9 of 1197
```
Test plan:
Run `utils/opt-viewer/opt-*.py` on a CentOS and macOS machine, using
Python 3.4 and Python 2.7 respectively, and ensure the output is
formatted well on both.

Summary:
opt-stats.py and opt-viewer.py's argument parsers both take a positional
argument 'yaml_files'. Positional arguments in Python's argparse module are
required by default, so the subsequent checks for `len(args.yaml_files) == 0`
are unnecessary -- if the length was zero, then the call to
`parser.parse_args()` would have thrown an error already.
Because there is no way for `len(args.yaml_files)` to be zero at these
points, removing the code is NFC.

Summary:
Python's argparse module includes a `%(default)s` format specifier that
can be used to print the default value of an option in its help text.
Use this for opt-viewer utilities' `--jobs` arguments.

I am planning to use this tool to find too noisy (missed) optimization
remarks. Long term it may actually be better to just have another tool that
exports the remarks into an sqlite database and perform queries like this in
SQL.
This splits out the YAML parsing from opt-viewer.py into a new Python module
optrecord.py.
This is the result of the script on the LLVM testsuite:
Total number of remarks 714433
Top 10 remarks by pass:
inline 52%
gvn 24%
licm 13%
loop-vectorize 5%
asm-printer 3%
loop-unroll 1%
regalloc 1%
inline-cost 0%
slp-vectorizer 0%
loop-delete 0%
Top 10 remarks:
gvn/LoadClobbered 20%
inline/Inlined 19%
inline/CanBeInlined 18%
inline/NoDefinition 9%
licm/LoadWithLoopInvariantAddressInvalidated 6%
licm/Hoisted 6%
asm-printer/InstructionCount 3%
inline/TooCostly 3%
gvn/LoadElim 3%
loop-vectorize/MissedDetails 2%
Beside some refactoring, I also changed optrecords not to use context to
access global data (max_hotness). Because of the separate module this would
have required splitting context into two. However it's not possible to access
the optrecord context from the SourceFileRenderer when calling back to
Remark.RelativeHotness.
