On case-insensitive file systems, the editor may send us a path that
works but doesn't match the actual file's case. Then when we run go
list, we'll get mismatching paths and everything will break.
We can't reliably fix this problem: tracking what case the editor
expects is too difficult to be worth it. Instead, check the workspace
path and bail if it's mismatched.
Possibly we should also check files on DidOpen or such, but we can start
with this.

Expressing regtests in terms of textual coordinates is hard to read: the
reader ends up counting lines and characters to understand the text edit
or assertion.
To address, this, add two new functions for fake.Editor: RegexpSearch
and RegexpReplace, as well as a symmetric RegexpSearch function for
workspace files and wrappers for regtext.Env.
This allows expressing edits as well as buffer locations in terms of
easily scannable regexps.
An alternative solution to this problem is to integrate markers ala
packagestest. I tried this, but it ended up being cumbersome to
implement and less usable than regexps, due to the static nature of
markers: after the buffer has been edited all markers must be
updated.

we print a view-specific `go env`, which will helps us when debugging
multi-project workspaces. Additional information included: the folder of
the view, if the view has a valid build configuration, and the build
flags for the view.

This is helpful for users to diagnose issues, but it annoys people who
have workspaces with both non-Go and Go projects. I'm going to spend
some more time thinking about this, particularly about which error

I'm not sure if this is entirely the correct approach, but at the very
least we should never pass "command-line-arguments" to packages.Load. We
still need to cache packages with the path "command-line-arguments" to
avoid an excessive number of calls to packages.Load.
