[PATCH] Refine the ARM EHABI test cases.

[Logan Chien]

  I tried to grep "\.section" in the test directory.  However, I can't find something equivalent.  The "ARM/darwin-section-order.ll" looks similar, but it is for Darwin (with different section name.)  It seems that there is no existing test for Linux.  Besides, the section name for the functions with the linkonce_odr linkage is not checked as well.
