Per Eli's feedbacks:
(1) a test case (windows-seh-abnormal-exit.c) is added under clang\test\CodeGen directory.  
(2) an assert is added to catch the extremely rare case that the number of JumpDests in a function is greater than 255.  The max. number of JumpDests is 1 (return) + 2*M + N, where M is the number of for/while-loops and N is the number of Goto targets.
