error on `where` variable name collision inside struct def

[krrutkow]

On official Julia 1.1 binaries:

struct BadStruct{T}
   t::T
   v::Vector{Tuple{T} where {T<:Integer}}
end

results in an error message like ERROR: syntax: invalid type parameter name "SSAValue(...)" which doesn't really help to identify the offending name.

This code should be valid, so this is just a bug.

(Workaround is to use a different name for one of the Ts.)

looks like it was fixed in 1.12
