Reapply: [mips] Handle MipsMCExpr sub-expression for the MEK_DTPREL tag This reapplies commit r351987 with a failed test fix. Now the test accepts both DW_OP_GNU_push_tls_address and DW_OP_form_tls_address opcode. Original commit message: ``` This is a fix for a regression introduced by the rL348194 commit. In that change new type (MEK_DTPREL) of MipsMCExpr expression was added, but in some places of the code this type of expression considered as unexpected. This change fixes the bug. The MEK_DTPREL type of expression is used for marking TLS DIEExpr only and contains a regular sub-expression. Where we need to handle the expression, we retrieve the sub-expression and handle it in a common way. ``` llvm-svn: 352034

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144
