Change ASSERTs for failures to find items in a hashmaps to ASSERT_WITH_SECURITY_IMPLICATIONs. This results in an out-of-bounds memory access as the iterator is equal to hash map's end and we try to read/write to that location.

Support full range of PreflightPolicy over WebURLLoaderOptions

Allow users of WebURLLoader to state the preflight behavior to follow
for the request. This is done so that the user/caller can explicitly
control when its author header set
(http://www.w3.org/TR/cors/#author-request-headers) is empty, then no
preflight must be performed.

This puts the responsibility on the caller to adhere to CORS and not
disable preflighting when the author set is non-empty or the request
is over non-simple methods (http://www.w3.org/TR/cors/#simple-method )

The WebURLLoaderOptions default is ConsiderPreflight.
