And fix a review issue from #16154.

If there's a cleaner place to put these methods to avoid redefinition warnings, suggestions are welcome. Symbol is a builtin type and base/expr.jl gets included both in coreimg.jl and sysimg.jl, but looks like the vararg Symbol constructor is not needed in Inference (and string isn't defined yet there anyway).

there are dot operators that are more than 2 characters long that these
loops may want to extend to in the future, leaving the 2:end the way it
was will be less error prone
expr.jl is included in both Inference and Base, so split these methods
into coreimg.jl and sysimg.jl
Symbol(s::UTF8String) = Symbol(s.data)
Symbol(a::Array{UInt8,1}) =
ccall(:jl_symbol_n, Ref{Symbol}, (Ptr{UInt8}, Int32), a, length(a))

I think most of the builtin type constructors are defined in boot.jl. Putting it here should be good also as long as nothing before this depends on it.

and an unnecessary identity method
