support for for-else and while-else

companion to JuliaLang/julia#56153

The upstream reception of this seems overall negative, so I guess we might not do it?

A minor comment if we do ever merge this - for tests we should never depend on VERSION unless really necessary: JuliaSyntax is multi-version aware :)

Suggested change

	if VERSION >= v"1.12-"
	@test parsestmt("for x=xs\ny\nelse\nz\nend") ==
	Expr(:for,
	Expr(:(=), :x, :xs),
	Expr(:block,
	LineNumberNode(2),
	:y,
	),
	Expr(:block,
	LineNumberNode(4),
	:z,
	LineNumberNode(5)
	)
	)
	end
	@test parsestmt("for x=xs\ny\nelse\nz\nend", version=v"1.12") ==

Heya, we just moved JuliaSyntax into Base in JuliaLang/julia#59870 - if you want to re-propose this PR over there, I've created a branch https://github.com/JuliaLang/JuliaSyntax.jl/tree/pr-for-Base/513 to make this easier.

To make use of the branch, you can use the following steps:

• Clone JuliaLang/julia
• Add JuliaSyntax as a git remote
• Check out pr-for-Base/513
• Rebase on top of master

For example:

# git clone git@github.com:JuliaLang/julia julia_dir
# cd julia_dir

git remote add JuliaSyntax git@github.com:JuliaLang/JuliaSyntax.jl
git fetch JuliaSyntax
git checkout pr-for-Base/513
git rebase origin/master

Sorry this wasn't dealt with prior to the big move!
