Haojian Wu f5b5426433 [clang] Fix a crash on CheckArgAlignment.
We might encounter an undeduced type before calling getTypeAlignInChars.

NOTE: this retrieves the fix from
8f80c66bd2, which was removed in Adam's
followup fix fbfcfdbf68. We originally
thought the crash was caused by recovery-ast, but it turns out it can
occur for other cases, e.g. typo-correction.

Haojian Wu 16ca711803 [clang] Fix a typo-correction crash
We leave a dangling TypoExpr when typo-correction is performed
successfully in `checkArgsForPlaceholders`, which leads a crash in the
later TypoCorrection.

This code was added in 1586782767,
and it didn't seem to have enough test coverage.
The fix is to remove this part, and no failuer tests.

Sam McCall 835d67f6c7 [Sema] Correct typos in return statements so the return types of 'auto' functions are always deduced.
Summary:
e.g.
  auto foo() {
    return no_such_thing; // Return value is a TypoExpr
  }
  using T = decltype(foo()); // Uh-oh, undeduced auto.

Richard Smith b8c414ccd1 Fix typo-correction crash if a typo occurs within the operand of a
function-style cast to a non-dependent type which is then used in an invalid
way. We'd lose the "type dependent" bit here, and downstream Sema processing
would then discard the expression if it was used in a context where its type
rendered it invalid.

Reid Kleckner 4ce625c814 [typo-correction] Apply name specifier corrections when forming a NNS
Previously we would leave behind the old name specifier prefix, which
creates an invalid AST.  Other callers of CorrectTypo update their
CXXScopeSpec objects with the correction specifier if one is present.

Manman Ren b4e8a1b308 Fix a crash when there is a typo in the return statement.
If the typo happens after a successful deduction for an earlier
return statement, we should check if the deduced type is null
before using it.

The typo correction happens after we try to deduce the return
type and we ignore the deduction from the typo and continue
to typo correction.
