Fixes errors of the following kind, which happen when dump-decls is run on a package that contains a module name that clashes with that of another package.
```
dump-decls: <no location info>: error:
Ambiguous module name `System.Console.ANSI.Types':
it was found in multiple packages:
ansi-terminal-0.11.4 ansi-terminal-types-0.11.5

Expands do notation before typechecking using `HsExpansion`
- Adds testcases T18324, T18324b, DoubleMatch
Expands
- Do statements
- Monadic do statements
- monadic fix blocks
- make sure fail is used for pattern match failures in bind statments
- Makes sure unused binds generate warnings
- runs the pattern match check in generated lambda exprs to avoid getting suprious pattern match failures. c.f. pmcheck/should_compile/DoubleMatch.hs
- PopSrcSpan in HsExpr to pop error context
- Discards default monad fail alternatives that are spuriously generated
- Make sure we check for generated loc span for checking if the (>>) is user written or expanded for /do/ purposes
- Add PopSrcSpan (XXExprGhcRn) in appropriate places while expanding statements
- correct source spans displayed for warnDiscardedDoBindings
- use `mkExpandStmt` to store original stmts along with expanded expr for using the right context for error message printing
- improves error messages for applicative do
- remove special case from isMatchContextPmChecked (long distance info is now properly propogated)
- set correct src spans to statement expansions
- Match ctxt while type checking HsLam is different if the lambda match is due to an expression generated from a do block
- call tcExpr and not tcApp in PopSrcSpan so make sure impredicativity works fine
- look into XExprs in tcInferAppHead_maybe for infering the type to make T18324 typecheck and run
- make the ExpandedStmt generated expression location-less
- Introduce ExpansionStmt for proper `hsSplitApps`
- Introduce `VAExpansionStmt` that is just like `VAExpansion` but for statements
- Aligning expand stmt context pushing on error stack.
- Pop error context while checking do expansion generated GRHSs inside HsLam so that we do not print the previous statement error context
- makes template haskell happy
- some fix for let expansions
- refactor tcExpr into tcExpr and tcXExpr
- adding Note and references
- make monad fail errors normal again
