Verifier: Reject any unknown named MD nodes in the llvm.dbg namespace. This came out of a discussion in https://reviews.llvm.org/D25285. There used to be various other llvm.dbg.* nodes, but we don't support upgrading them and we want to reserve the namespace for future uses. This also removes an entirely obsolete and bitrotted testcase for PR7662. Reapplies 283390 with a forgotten testcase. llvm-svn: 283400

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922
