Subject: IR: MDNode => Value: Instruction::setMetadata()
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=815275f5de3ce5d79a1d399d2ba86177c4de1aa5

IR: MDNode => Value: Instruction::setMetadata()

Change `Instruction::setMetadata()` API to accept `Value` instead of
`MDNode`.  Part of PR21433.
