This lurking bug used the wrong function to compare two
types in GHC.Tc.Module.checkBootTyCon
It's hard to trigger the bug, which only came up during
!9343, so there's no regression test in this MR.

This patch fixes pretty-printing of character literals
inside promoted lists and tuples.
When we pretty-print a promoted list or tuple whose first element
starts with a single quote, we want to add a space between the opening
bracket and the element:
'[True] -- ok
'[ 'True] -- ok
'['True] -- not ok
If we don't add the space, we accidentally produce a character
literal '['.
Before this patch, pprSpaceIfPromotedTyCon inspected the type as an AST
and tried to guess if it would be rendered with a single quote. However,
it missed the case when the inner type was itself a character literal:
'[ 'x'] -- ok
'['x'] -- not ok
Instead of adding this particular case, I opted for a more future-proof
solution: check the SDoc directly. This way we can detect if the single
quote is actually there instead of trying to predict it from the AST.
The new function is called spaceIfSingleQuote.
