[ros-svn] [ion] 20923: - Fix a build issue.

[ion at svn.reactos.org]

- Fix a build issue.
- Added more DBG checks for trap exits:
  * Detect if exiting with incorrect IF state.
  * Detect if exiting with broken stack.
  * Detect if exiting with a broken trap frame (note: Disabled in Kei386EoiHelper beause this raises the assertion. The trap frame is valid, it's just that some old code is using DbgArgMark for other purposes. Will fix.)
  * Detect if exiting with invalid FS.
  * Detect if exiting with invalid Exception List.
  * Detect if exiting with incorrect exception list and/or incorrect previmous mode on the stack (to detect macro/calling type mismatch).
The trap exit code is now complete and shareable across all 3 trap exit types, except for one broken assertion left to fix.
