inlined code line numbers need work #13725
Description
Example (encountered while working on #13547):
julia> Array{Type{Int64}}([Float32])
ERROR: TypeError: copy!: in typeassert, expected Type{Int64}, got Type{Float32}
[inlined code] from operators.jl:313
in copy! at abstractarray.jl:301
[inlined code] from abstractarray.jl:112
in call at essentials.jl:116
The line abstractarray.jl:301 is correct, but the other 3 line numbers are completely wrong. I believe the fix is for the inliner to insert some kind of location "pop" operation. For example we have
julia> @code_typed Array{Type{Int64}}([Float32])
1-element Array{Any,1}:
:($(Expr(:lambda, Any[symbol("#s1"),:arg], Any[Any[Any[symbol("#s1"),Type{Array{Type{Int64},N}},0],Any[:arg,Array{DataType,1},0]],Any[],Any[Int64,Int64,Array{Type{Int64},1}],Any[:T]], :(begin # essentials.jl, line 58: # array.jl, line 229: # array.jl, line 230: # array.jl, line 158: # array.jl, line 48:
GenSym(0) = (Base.arraysize)(arg::Array{DataType,1},1)::Int64 # essentials.jl, line 204: # essentials.jl, line 194: # essentials.jl, line 114: # essentials.jl, line 61: # essentials.jl, line 116:
...
We see several line nodes piled up, without knowing their nesting structure.
