compiler: don't lift top-level lambdas.
The compiler is lifting top-level lambdas, such as those
generated by defun, using the load-time mechanism. This has
the undesireable effect of unnecessarily placing the lambdas
into a D register.
* stdlib/compiler.tl (*top-level*): New special variable.
This indicates that the compiler is compiling code that
is outside of any lambda.
(compiler comp-lambda-impl): Bind *top-level* to nil when
compiling lambda, so its interior is no longer at the
top level.
(compiler comp-lambda): Suppress the unnecessary lifting
optimization if the lambda expression is in the top-level,
outside of any other lambda, indicated by *top-level* being
true.
(compile-toplevel): Bind *top-level* to t.
