This CL updates test/run.go to compile xxx.dir/x.go with a package
path of "test/x" instead of just "x". This prevents collisions with
standard library packages.
It also requires updating a handful of tests to account for the
updated package paths.
Fixes#25693.

I was testing edge cases in gofumpt, a fork of gofmt,
and noticed that gofmt will return a bare io error on empty files,
as demonstrated by the added test case without a fix:
> ! exec $GOROOT/bin/gofmt empty.go nopackage.go
[stderr]
EOF
nopackage.go:1:1: expected 'package', found not
The problem is the code that detects concurrent modifications.
It relies on ReadFull and correctly deals with io.ErrUnexpectedEOF,
but it did not pay attention to io.EOF, which can happen when size==0.

The file names reported in error messages by the compiler are
printed unchanged from the file names provided to the compiler;
the -L flag has no impact on the file names themselves, contrary
to what the old flag description suggested.
If an error is reported on a line that is affected by a //line
directive, an error message reports the file name and line as
controlled by the directive (i.e., the actual source position
is not known).
If the -L flag is provided, the actual source position is also
reported in square brackets.
This change documents this with an updated help string for the
flag.

bug302 compiles p.go with -p=p, and then manually creates a pp.a
archive, and imports it as both "p" and "pp". This is a misuse of
cmd/compile's -p flag, and it isn't representative of how any actual
Go build systems work anyway.
This test made sense back when cmd/compile still wrote out bare object
files, which was then split into separate __.PKGDEF and _go_.o archive
entries when added to a pack archive. But since CL 102236, cmd/compile
always writes out pack files.

Currently, run.go's *dir tests allow "x.go" to be imported
interchangeably as either "x" or "./x". This is generally fine, but
can cause problems when "x" is the name of a standard library
package (e.g., "fixedbugs/bug345.dir/io.go").
This CL is an automated rewrite to change all `import "x"` directives
to use `import "./x"` instead. It has no effect today, but will allow
subsequent CLs to update test/run.go to resolve "./x" to "test/x" to
avoid stdlib collisions.

The code iterates through the func table to find a function with
a given file and line number. The code panics if it sees a non-
