• fix ​http://bugs.webkit.org/show_bug.cgi?id=16370 REGRESSION (r28540): source URL and line number no longer set for outer function/programs

Test: fast/js/exception-linenums-in-html-1.html
Test: fast/js/exception-linenums-in-html-2.html
Test: fast/js/exception-linenums.html

By the time the ProgramNode was constructed, the source URL was empty.

• kjs/Parser.cpp: (KJS::Parser::parseProgram): Added code to set and clear m_sourceURL, which is now handled here instead of in the lexer; it needs to still be set when we create the program node. Call setLoc to set the first and last line number. (KJS::Parser::parseFunctionBody): Ditto, but for the body. (KJS::Parser::parse): Removed the sourceURL argument.

• kjs/Parser.h: Added sourceURL(), m_sourceURL, and m_lastLine. Added a lastLine parameter to didFinishParsing, since the bison grammar knows the last line number and we otherwise do not know it. Removed the sourceURL parameter from parse, since that's now handled at a higher level.

• kjs/grammar.y: Pass the last line number to didFinishParsing.

• kjs/lexer.cpp: (KJS::Lexer::setCode): Removed the sourceURL argument and the code to set m_sourceURL. (KJS::Lexer::clear): Ditto.
• kjs/lexer.h: More of the same.

• kjs/nodes.cpp: (KJS::FunctionBodyNode::FunctionBodyNode): Get the source URL from the parser rather than from the lexer. Removed unneeded call to setLoc, since the line numbers already both default to -1.
