fail to compile the examples

[gftea]

I tried to compile the examples below

rustup +nightly component add rust-src rustc-dev llvm-tools-preview
rustc +nightly rustc-driver-interacting-with-the-ast.rs 

I got below errors

As noted in https://rustc-dev-guide.rust-lang.org/rustc-driver-interacting-with-the-ast.html#getting-the-type-of-an-expression:

To get the type of an expression, use the global_ctxt to get a TyCtxt. The following was tested with nightly-2022-06-05 (see here for the complete example):

A PR is welcome to update the nightly version :)
