sample HTML with onload handler

If the HTML has a JScript OnLoad handler it gets called with VBScript host and
leads to a crash because of a infinite recursion. Infinite recursion in
vbscript is probably a separate bug, and is not important for purposes of this
bug report.
What is important is that JScript OnLoad handler is not called.

Attached onload.html illustrates this bug:

wine iexplore file:///onload.html

wine: Unhandled stack overflow at address F7D68D7D (thread 00c0), starting
debugger...
00c0:err:virtual:virtual_setup_exception stack overflow 1668 bytes in thread
00c0 addr 0x7bc338d5 stack 0x12097c (0x120000-0x121000-0x220000)

Jacek, this one is probably in your field of expertise.
