Allocate HIR on an arena #57173

Intrigued by this change, the previous formatting was correct.

There are a few of these changes were formatting is reverted to the formatting at the time I created the commit. Totally could use some rustfmt help.

Could you clean the indenting back to what it was here?

-pub struct LoweringContext<'a> {
+macro_rules! p {
+    ($this:expr, $e:expr) => ({
+        P::alloc($this.arena, $e)


I wonder if this could be just $this.alloc($e) and maybe then we wouldn't need a macro?
Then again, I think the macro allows nested allocations (e.g. p!(self, Foo(p!(self, Bar(...))))) without borrow conflicts, since $this.arena can just be copied.
