<pre>[WebCore][JSC] Use new @throwTypeError and @throwRangeError intrinsics
https://bugs.webkit.org/show_bug.cgi?id=163001
Reviewed by Keith Miller.
Source/JavaScriptCore:
Previously, the argument of @throwXXXError intrinsics must be string literal.
But it is error-prone restriction. This patch relaxes the restriction to accept
arbitrary values. To keep emitted bytecode small, if the argument is string literal,
we generate the same bytecode as before. If the argument is not string literal,
we evaluate it and perform to_string before passing to throw_static_error.

(JSC::BytecodeIntrinsicNode::emit_intrinsic_throwRangeError):
* dfg/DFGByteCodeParser.cpp:
(JSC::DFG::ByteCodeParser::parseBlock):
Source/WebCore:
Replace `throw new @XXXError(...)` to @throwXXXError intrinsic.
It reduces the size of bytecode sequence and facilitate inlining.
No behavior change.
