Fix spaceship operator bugs, document, add tests
...
Remove some erroneously added brackets_increment() calls.
Reject <=> in preprocessor expressions with a clear error message (it
seems it isn't supported here - clang and gcc don't at least).
The type returned by `<=>` is not `bool`. We pretend it's
`int` for now, which should work for how it's likely to be used
in constant expressions.
Fixes #1622

Don't report "Warning 202: Error: ..."
...
An invalid preprocessor expression is reported as a pair of
warnings with the second giving a more detailed message from the
expression evaluator. Previously SWIG prefixed the second message
with "Error:" - that was confusing as it's actually only a warning
by default so we've now dropped this prefix.
Before:
x.i:1: Warning 202: Could not evaluate expression '1.2'
x.i:1: Warning 202: Error: 'Floating point constant in preprocessor expression'
Now:
x.i:1: Warning 202: Could not evaluate expression '1.2'
x.i:1: Warning 202: Floating point constant in preprocessor expression

Fix a preprocessor expression evaluation bug
...
A subexpression in parentheses lost its string/int type flag and
instead used whatever type was left in the stack entry from
previous use. In practice we mostly got away with this because
most preprocessor expressions are integer, but it could have
resulted in a preprocessor expression incorrectly evaluating as
zero. If -Wextra was in use you got a warning:
Warning 202: Error: 'Can't mix strings and integers in expression'

Add suggestion to check block delimiter

The fix for #217 means that blocks of target code delimited by { } with
'#' comments in now give errors (previously these lines were quietly
discarded).
The fix is generally to use %{ %} delimiters instead, so suggest this
might be the issue in the error message to help users hitting this issue
with wrappers which were apparently working before.
