------- Additional Comments from Norbert Leser <norbert.leser at nokia.com>
This patch removes the -O3 -OTime compiler optimization for Symbian ARM release
targets. This one was initially introduced when JavaScriptCore was embedded in
WebCore's build but is not really necessary for WebCore. Sunspider and V8 tests
show no performance differences whatsoever.

However, removing this optimization reduces the runtime code size by 33%.
Counting the slight code size increase due to optimization in JavaScriptCore
only (6%), overall we'll still have 27% less code with a total of
(uncompressed) 9.8MB.
