<h3>Log Message</h3>
<pre>Simplify the initialization of BytecodeGenerator a bit
https://bugs.webkit.org/show_bug.cgi?id=141505
Reviewed by Anders Carlsson.
* bytecompiler/BytecodeGenerator.cpp:
(JSC::BytecodeGenerator::BytecodeGenerator):
* bytecompiler/BytecodeGenerator.h:
Setup the default initialization at the declaration level
instead of the constructor.
Also made m_scopeNode and m_codeType const to make it explicit
that they are invariant after construction.
* parser/Nodes.cpp:
* runtime/Executable.cpp:
Remove 2 useless #includes.</pre>
