4fe2432e05 Rework of REQUIRE* changes in CATCH_CONFIG_FAST_COMPILE 
`ResultBuilder`s destructor now checks for exceptions, preventing false
negatives. The speedup should remain the same give or take a tiny bit.

f23b6b8b85 Don't sanitize exception type in REQUIRE_THROWS_AS 
Effectively a revert of previous commit, fixing #542, where this was
added to stop linters complaining about `REQUIRE_THROWS_AS` used like
`REQUIRE_THROWS_AS(expr, std::exception);`, which would be slicing the
caught exception. Now it is user's responsibility to pass us proper
exception type.

Closes #833 which wanted to add `typename`, so that the construct works
in a template, but that would not work with MSVC and older GCC's, as
having `typename` outside of a template is allowed only from C++11
onward.

f3ec843ba6 Changed all internal forwarding macro usages to put macro name as first argument 
(and ‘expression’, if any, last)
This is a first step towards allowing expression arguments to become variadic

7a8a0205b4 CATCH_CONFIG_FAST_COMPILE now disables trys in REQUIRE* 
This seems to give about 15% speedup when compiling tests using GCC.

The tradeoff is that under certain circumstances, there is a chance for
false negative result, when the expression under test throws exception
and the test code catches it before it gets to the test runner.

Example:
``` cpp
TEST_CASE("False negative") {
try {
REQUIRE(throws() == "");
} catch (...) {}
}
```
This test case will succeed, reporting no assertions checked, instead of
failing as it would with `CATCH_CONFIG_FAST_COMPILE` disabled. However,
just removing the try-catch block inside client's code will fix this, so
it is worthwhile.

This change does not apply to CHECK* macros, because these are currently
specified as continuing on exception and thus need the local try-catch
to work as intended.

0dabd951ba expr is now cast to void in THROWS family of assertions. 
This prevents Clang from complaining about unused value in expressions
containing explicit casts used in the THROW assertion macro family.

Example:
`REQUIRE_THROWS_AS(static_cast<bool>(object), std::bad_cast);` would
trigger `-Wunused-value` warning. Now it does not.

Credits to Arto Bendiken, who submitted a PR almost 3 years ago, but his
branch has since died and I was unable to merge it.

15816c5760 Revert "use sizeof(expr) for unevaluated syntax check" 
Using sizeof(expr) can trigger a compile-time error,
"lambda expressions are not allowed in an unevaluated context", when passing
expression containing lambda, like a std algorithm. This error is considered
a standard defect, as it is meant to prevent lambdas in decltype
or templates, but not in sizeof.

This reverts commit 227598af47.

184865358c CHECK no longer stops running SECTION on exception. 
This seems to be much closer to desired behaviour than the current one, where
CHECK(false) lets the execution continue, but CHECK(<throws>) does not.

9438a03d5b Big assertion capture refactoring. 
- moved as much logic out of the macros as possible
- moved most logic into new ResultBuilder class, which wraps ExpressionResultBuilder (may take it over next), subsumes ResultAction and also takes place of ExpressionDecomposer.

This introduces many SRP violations - but all in the name of minimising macro logic!
