Deduplicate identical entries in "code methods X"

[mahrud]

Before:

o1 = -- code for method: toList(BasicList)
     function toList1: source code not available
     ---------------------------------------------------------------------------
     -- code for method: toList(Set)
     function toList1: source code not available
     ---------------------------------------------------------------------------
     -- code for method: toList(String)
     function toList1: source code not available
     ---------------------------------------------------------------------------
     -- code for method: toList(Thing)
     ../linuxbrew/.linuxbrew/share/Macaulay2/Core/iterators.m2:28:18-28:37:
     --source code:
     toList Thing := x -> for y in x list y

After:

o1 = -- code for method: toList(Thing)
     ../../../../feature/M2/Macaulay2/m2/iterators.m2:29:18-29:37:
     toList Thing := x -> for y in x list y
     ------------------------------------------------------------------------------------------------------------------------
     -- code for method: toList(String)
     -- code for method: toList(BasicList)
     -- code for method: toList(Set)
     compiled function toList1: source code not available

Also sorts the methods by location, rather than name:

i3 : locate methods(map, Module, List)

o3 = {0 => (../../../../feature/M2/Macaulay2/m2/matrix1.m2:93:45-157:10) }
     {1 => (../../../../feature/M2/Macaulay2/m2/matrix1.m2:93:45-157:10) }
     {2 => (../../../../feature/M2/Macaulay2/m2/matrix1.m2:93:45-157:10) }
     {3 => (../../../../feature/M2/Macaulay2/m2/ringmap.m2:568:47-568:94)}
     {4 => (../../../../feature/M2/Macaulay2/m2/ringmap.m2:569:48-569:84)}

Closes #3364.

Interesting, I think this failure means the hashes of autotools and cmake builds are different.

What happened?

What happened?

This failed with CMake but not on Autotools:

i81 : s = code methods u

o81 = -- code for method: u(Matrix)
      -- code for method: u(Number)
      compiled function identity: source code not available

i82 : assert(net s#0#0 == "-- code for method: u(Number)")

Presumably because on Autotools Matrix and Number lines above are flipped :)

I don't think it's an autotools v. cmake thing, but just that the hash of the method function u depends on its address in memory after #2934.
