Use fully qualified namespace name.

llvm::detail is not the only namespace named detail.  So if
someone has done a `using namespace llvm::support`, for example,
this will fail with an ambiguous namespace name.  Granted
people generally shouldn't be using large namespaces like that,
but it's common at local function scopes.
