Sync to Wine-0_9_4:
Alexandre Julliard <julliard at winehq.org>
- winebuild: Allow -register flag for Win32 too.
This way it can be used as hint for the relay code.
- ntdll: Make __wine_call_from_32_restore_regs take a context pointer.
Changed exception raise functions to call it explicitly.
- ntdll: New implementation of relay thunks.
New implementation of relay thunks that doesn't require modifying code
on the fly, so that the thunks can be put in the text section.
Some performance improvements.
