[mips] Handle R_MIPS_TLS_DTPREL32/64 relocations in the RelocVisitor Debug information for TLS variables on MIPS might have R_MIPS_TLS_DTPREL32 or R_MIPS_TLS_DTPREL64 relocations. This patch adds a support for such relocations in the `RelocVisitor`. llvm-svn: 311031 2017-08-16 19:01:22 +00:00			`; RUN: llc -O0 -march=mips -mcpu=mips32r2 -filetype=obj -o=%t-32.o < %s`

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 2017-08-30 18:06:51 +00:00			`!0 = !DIGlobalVariableExpression(var: !1, expr: !DIExpression())`
