[Settings] Replace current Settings generation with template file based approach
​https://bugs.webkit.org/show_bug.cgi?id=178634

Patch by Sam Weinig <​sam@webkit.org> on 2017-10-22
Reviewed by Joseph Pecoraro.

This replaces the recently added python based Settings generation with a generator
built in ruby, so we can take advantage of ERB for templating. The result has much
of the logic in the templates and as a result feels much easier to follow and cleaner.

Since I was moving things to ruby, I took the opertunity to switch the Settings definition
file from our .in format to yaml, which is quite a bit easier to read.

[iOS] WebProcess::initializeWebProcess spends ~150ms spinning up AVSystemController on some devices

<rdar://problem/35113105>

Reviewed by Youenn Fablet.

In r213933, we added a mechanism to allow the web process to drive media capture, by setting an attribute on the
shared AVSystemController. This requires us to fault in the Celestial framework, which is a slight performance
hit on some hardware. Instead of doing this at the start of every web process launch, we can just do this work
lazily, the first time the web process requests permissions for user media access.

[JSC][Baseline] Use linkAllSlowCasesForBytecodeOffset as much as possible to simplify slow cases handling
​https://bugs.webkit.org/show_bug.cgi?id=178647

Reviewed by Saam Barati.

There is much code counting slow cases in fast paths to call linkSlowCase carefully. This is really error-prone
since the number of slow cases depends on values of instruction's metadata. We have linkAllSlowCasesForBytecodeOffset,
which drains all slow cases for a specified bytecode offset. In typical cases like just calling a slow path function,
this is enough. We use linkAllSlowCasesForBytecodeOffset as much as possible. It significantly simplifies the code.

[JSC] Clean up baseline slow path
​https://bugs.webkit.org/show_bug.cgi?id=178646

Reviewed by Saam Barati.

If the given op is just calling a slow path function, we should use DEFINE_SLOW_OP instead.
It is good since (1) we can reduce the manual emitting code and (2) it can clarify which
function is implemented as a slow path call. This patch is an attempt to reduce 32bit specific
code in baseline JIT.
