This is in preparation to the removal of the FullCodeGenerator, we no
longer need the ability to stress the underlying implementation.

Removes the --ignition flag which is now on by default. Adds a
--stress-fullcodegen flag which enables running all functions supported
by fullcodegen to be compiled by fullcodegen.
This will enable moving parser internalization later when we are not
stressing fullcodegen or compiling asm.js functions.

Move dead bytecode elimination from a seperate bytecode pipeline optimizer
into the BytecodeArrayWriter. This removes the last bytecode pipeline
optimizer, which means we can remove the Bytecode pipeline which,
which should increase compile speed.

All the optimizations have now been moved to either the BytecodeGenerator
or the BytecodeArrayWriter/Builder.

Downside: this adds all kinds of weird includes in the .cc files.

This makes for slightly faster rebuilds when touching parser-base.h
(which changes frequently!). Also takes care of an old TODO,
moving CompileTimeValue into its own file under ast/, where it
properly belongs.

With this change the bytecode array builder only emits expression
positions for bytecodes that can throw. This allows more peephole
optimization opportunities and results in smaller code.

The optimization stages in the bytecode generation pipeline must
preserve source position information. Failure to preserve
source position information could result in single stepping
in the debugger misbehaving or mis-reporting in exception stack traces.
This change adds tests intended to check optimizations do not damage
source position info.
