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.

This flag is on by default for now. Whenever heuristics in the compiler
pipeline decide to use Ignition+TurboFan, then {BytecodeGraphBuilder} is
active. Removing the flag reduces maintenance overhead.

This adds an explicit {OsrPoll} bytecode into every loop header which
triggers on-stack replacement when armed. Note that each such bytecode
stores the static loop depths as an operand, and hence can be armed for
specific loop depths.
This also adds builtin code that triggers OSR compilation and switches
execution over to optimized code in case compilation succeeds. In case
compilation fails, the bytecode dispatch just continues unhindered.
