Without some hook like this, it's impossible to get a $ into the generate
command, which is necessary if you're trying to do some shell scripting
or regular expressions.
We could use backslash escaping but that's already tricky enough
because the strings are processed as Go strings. Using $ like this
means we need no more mechanism, just a predefined variable.
We may need to revisit this but I hope we can avoid new quoting rules.

Split out from cl/8024 for clarity and improved approach.
Rarely, "stop reason = breakpoint" does not appear in the lldb stop
text. However the program is ready to proceed. To be a little more
robust about those cases, we wait for two seconds, and if that text
doesn't appear but a prompt does we continue and hope for the best.
Worst case, this results in a harder to read failure message.

When external linking, we must link to implib provided by mingw, so we must use
properly decorated names for stdcalls.
Because the feature is only used in the runtime, I've designed a new decoration
scheme so that we can use the same decorated name for both 386 and amd64.
A stdcall function named FooEx from bar16.dll which takes 3 parameters will be
imported like this:
//go:cgo_import_dynamic runtime._FooEx FooEx%3 "bar16.dll"
Depending on the size of uintptr, the linker will later transform it to _FooEx@12
or _FooEx@24.
This is in prepration for the next CL that adds external linking support for
windows/386.

Fix parsing of `import foo "foo" // indirect` lines. Previously, this
was treated as an import of package path `"foo" // indirect`, which
could result in the cycle-detection code failing to detect a cycle
because it would be treated as a separate package from `"foo"`.
Also, since there are theoretically multiple quoted forms for a
package path, use strconv.Unquote to normalize them. Side benefit:
Unquote will complain if any trailing comments sneak back in.
Aside: For most Go archives, Go package data is only present in the
__.PKGDEF member, but unless -u is used, ldpkg is only called on the
_go_.6 member. Consequently, importcycles is a no-op when -u isn't
used as it has no package data to inspect.

Previously, running 'go get' with a local path would correctly
download the package but fail to install it.
This is because a sticky error - resulting from discovering that the
package needed to be downloaded - was still around.
Theoretically, such sticky errors would be cleared but they weren't
because the map tracking these errors were indexed with the correct
canonical import path of the package (e.g. "ex.com/x/pkg") whereas the
clearing was done with the local path (e.g. "./pkg".)
Always use the canonical import path.
