Only exit ghci in -e mode when :add command fails

Previously, when running `ghci -e ':add Sample.hs'` the process would
exit with exit code 1 if the file exists and could be loaded.

Fixes #24115

T2T in Patterns (#23739)

This patch implements the T2T (term-to-type) transformation in patterns.
Patterns that are checked against a visible forall can now be written
without the `type` keyword:

	  \(type t) (x :: t) -> ...   -- old
	  \t (x :: t) -> ...          -- new

The `t` binder is parsed and renamed as a term pattern (Pat), but
then undergoes a conversion to a type pattern (HsTyPat).
See the new function pat_to_type_pat in compiler/GHC/Tc/Gen/Pat.hs

Pmc: Fix SrcLoc and warning for incomplete irrefutable pats (#24234)

Before, the source location would point at the surrounding function definition,
causing the confusion in #24234.
I also took the opportunity to introduce a new `LazyPatCtx :: HsMatchContext _`
to make the warning message say "irrefutable pattern" instead of "pattern
binding".

Zap OccInfo on case binders during StgCse #14895 #24233

StgCse can revive dead binders:

  case foo of dead { Foo x y -> Foo x y; ... }
  ===>
  case foo of dead { Foo x y -> dead; ... } -- dead is no longer dead

So we must zap occurrence information on case binders.

Fix #14895 and #24233

driver: Don't lose track of nodes when we fail to resolve cycles

The nodes that take part in a cycle should include both hs-boot and hs files,
but when we fail to resolve a cycle, we were only counting the nodes from the
graph without boot files.

Fixes #24196
