* capturing is useless per se, e.g. in test() check;
* captured groups are not used afterwards at all;
* some of the later captured groups are not used afterwards.

Imprecision in process.hrtime() in some situations can result in a zero
duration being used as a denominator in benchmark tests. This would
almost certainly never happen in real benchmarks. It is only likely in
very short benchmarks like the type we run in our test suite to just
make sure that the benchmark code is runnable.
So, if the environment variable that we use in tests to indicate "allow
ludicrously short benchmarks" is set, convert a zero duration for
a benchmark to 1 nano-second.

Some benchmark tests are failing intermittently, possibly due to
hrtime() imprecision on particular hosts. This change will confirm or
refute that as the root cause the next time the test fails on CI. Either
way, it's a valid check.

This removes the need for parsing stdout from the benchmarks. If the
process wasn't executed by fork, it will just print like it used to.
This also fixes the parsing of CLI arguments, by inferring the type
from the options object instead of the value content.
Only two benchmarks had to be changed:
* http/http_server_for_chunky_client.js this previously used a spawn
now it uses a fork and relays the messages using common.sendResult.
* misc/v8-bench.js this utilized that v8/benchmark/run.js called
global.print and reformatted the input. It now interfaces directly
with the benchmark runner global.BenchmarkSuite.

This commit optimizes checkInvalidHeaderChar() by unrolling the
character checking loop a bit.
Additionally, some changes to the benchmark runner are needed in
order for the included benchmark to be run correctly. Specifically,
the regexp used to parse `key=value` parameters contained a greedy
quantifier that was causing the `key` to match part of the `value`
if `value` contained an equals sign.

Other lint rules may have subtle performance implications in the V8

review and will be in a separate change.

The benchmark runner spawns new processes for each configuration. The
specific configuration is transfered by process.argv. This means that
the values have to be parsed. As of right now only numbers and strings
are parsed correctly. However other values such as objects where used.
This fixes the benchmarks that used non-string/number values and
prevents future issues by asserting the type.

This commit adds an `OUTPUT_FORMAT` environment variable option for

output has been left unchanged, and csv output prints out the csv
headers along with the csv formatted per-test output, each test also
seperated by a newline.
It can be used like the following:

Not specifying the OUTPUT_FORMAT env var will default to 'default'.
Specifying a bad value will throw an error.
