Re: [llvm-commits] llvm-gcc: support for NON_LVALUE_EXPR

 According to the docs:

 NON_LVALUE_EXPR
 These nodes indicate that their one and only operand is not an lvalue.
 A back end can treat these identically to the single operand.

 And that is what this patch does.

Applied, thanks.  Please check in the testcase.
