  Changed paths:
    M llvm/lib/CodeGen/GlobalMerge.cpp
    A llvm/test/Transforms/GlobalMerge/eh-filter.ll

  Log Message:
  -----------
  [GlobalMerge] Ensure that the MustKeepGlobalVariables has all globals from each landingpad clause.

The filter clause in the landingpad may not have a GlobalVariable operand.
It may instead have a ConstantArray of operands and each operand within this
ConstantArray should also be checked to see if it is a GlobalVariable.

This patch add the check for the ConstantArray as well as a debug message that
outputs the contents of MustKeepGlobalVariables.
