`hclparse` package comment references nonexistent functions

[ChandlerSwift]

The comment at the top of the hclparse package references hcl.SimpleParse, hcl.SimpleParseFile, and gohcl.SimpleDecode:

hcl/hclparse/parser.go

Lines 7 to 11 in 2efc266

	// The main HCL package also includes SimpleParse and SimpleParseFile which
	// can be a simpler interface for the common case where an application just
	// needs to parse a single file. The gohcl package simplifies that further
	// in its SimpleDecode function, which combines hcl.SimpleParse with decoding
	// into Go struct values

However, I was unable to find reference to any of these, e.g. the only reference to SimpleParse in this repo is in the hclparse package comment:

https://github.com/search?q=repo%3Ahashicorp%2Fhcl%20SimpleParse&type=code

I'm guessing this may be a holdover from hcl/v1 and isn't applicable to hcl/v2.

Should the comment either be updated to point at the correct resources or removed?

I think this comment is trying to refer to what became the functions in package hclsimple.

We rearranged the code a bunch just before tagging the v2.0.0 release and so I think this comment is describing one of the earlier arrangements we had.
