[AVR] Remove an assertion that causes generic CodeGen tests to fail

Browse Source 
It was discussed a few years ago and agreed that it makes sense to
remove this assertion as other targets do not perform similar register
size checking in inline assembly constraint logic, so the check just
adds a needless barrier on AVR.

This patch removes the assertion and removes 'XFAIL' from two Generic
CodeGen tests for AVR as a result.
