plt-racket 6.1
plt-racket: update 6.1 bottle.

Closes #31308.
Remove an is_a check
Don't pass nil to fails_with?
Rename compiler attribute to name
Move compiler failure matching logic into failure object
Use a separate class for GNU compiler failures

major_version is now only used internally by the failure object
Eliminate consideration of major_version

The major version is implicit in the compiler name. Since the name is
used when matching failures to compilers, we don't need to consider the
major version separately.
