tree-optimization/103190 - fix assert in reassoc stmt placement with asm

Browse source 
This makes sure to only assert we don't run into a asm goto when
inserting a stmt in reassoc, matching the condition in
can_reassociate_p.  We can handle EH edges from an asm just like
EH edges from any other stmt.

	PR tree-optimization/103190
	* tree-ssa-reassoc.c (insert_stmt_after): Only assert on asm goto.
