Subject: [PATCH] (everywhere): Correct range is -0x1fffffff to 0x20000000,
 others have to be loaded with movd.

(everywhere): Correct range is -0x1fffffff to 0x20000000, others have to be
loaded with movd.
Shortcircuit with TARGET_32532 as early as possible.
(movsi): Use movd to load unknown symbol values. to allow
