* Make control flow a bit easier, and more similar to previous code
Made similar to around line 790
* In a cpp11init, always parse only the corresponding } (#11134)
- _always_, because in some cases this was omitted (around line 790) or too strict (around line 860)
- _only_, and not following tokens which happen to be } as well (around line 1030)
* Fix unit tests: AST was incorrect, now is fixed
auto var{ {{},{}}, {} };
Old AST:
```
{
|-var
`-{
`-,
|-,
| |-{
| `-{
`-{
```
New AST:
```
{
|-var
`-,
|-{
| `-,
| | |-{
| | `-{
`-{
```
Compare the same example, but with `X{}` instead of just `{}`:
`auto var{ a{b{},c{}}, d{} };`
```
{
|-var
`-,
|-{
| |-a
| `-,
| | |-{
| | | `-b
| | `-{
| | | `-c
`-{
`-d
```
This structure is similar to that of the new AST, not the old AST
* Fix unit tests: another AST was incorrect, now is fixed
Code: `auto var{{1,a::b{2,3}}, {4,a::b{5,6}}};`
Old AST:
```
{
|-var
`-{
`-,
|-,
| |-1 'signed int'
| `-{
| | |-::
| | | |-a
| | | `-b
| | `-,
| | | |-2 'signed int'
| | | `-3 'signed int'
`-{
`-,
|-4 'signed int'
`-{
|-::
| |-a
| `-b
`-,
|-5 'signed int'
`-6 'signed int'
```
New AST:
```
{
|-var
`-,
|-{
| `-,
| | |-1 'signed int'
| | `-{
| | | |-::
| | | | |-a
| | | | `-b
| | | `-,
| | | | |-2 'signed int'
| | | | `-3 'signed int'
`-{
`-,
|-4 'signed int'
`-{
|-::
| |-a
| `-b
`-,
|-5 'signed int'
`-6 'signed int'
```
* Fix unit tests: missing ; after class, resulting in incorrectly being marked as cpp11init
Because of the missing `;` after the class declaration, it was marked as a cpp11init block.
Which it isn't, and which now throws an exception
* Fix cpp11init to let unit tests pass again
The following unit tests failed on the newly introduced throws, because the code for these tests incorrectly marked some tokens as cpp11init:
TestVarID::varid_cpp11initialization
TestTokenizer::checkRefQualifiers
* Fix typo
* Improve check for void trailing return type
Observation: the only function body _not_ containing a semicolon, is a void function: something like
auto make_zero(ini& i) -> void {
while(--i > 0) {}
}
Non-void function? Then it must return a value, and thus contain a semicolon, which is checked for a few lines later.
* Fix cpp11init with templated trailing return type
In the following example, vector was marked as cpp11init due to the mismatch of `%any% {`
auto f() -> std::vector<int> { return {}; }
I made the assumption that whenever "%any% {" matches, endtok must be set too.
If this assumtion doesn't hold (so "%any% {" matches, but endtok == nullptr), then the for-loop would search all the way to the end of stream. Which I guess was not the intention.
* Remove comments

* Don't simplify template for class names in declarations
Without the patch, the test would give:
```
Expected:
namespace foo { class Bar ; } class Baz ; class C : Baz { } ;
Actual:
namespace foo { class Bar ; } class Baz ; class foo :: Bar : Baz { } ;
```
* Use valid code in test case
`__typeof__` is just an alternative keyword for `typeof`, see
https://gcc.gnu.org/onlinedocs/gcc/Typeof.html
Since `typeof` is handled in several checkers it makes sense to define
`__typeof__` as `typeof`.
Tokenizer::simplifyTypedef(): Use `typeof` instead of `__typeof__` to
be consistent with the rest of the code.
* Better handle const/noexcept methods/conversion operator
const or noexcept in a method / (conversion) operator definition were
badly parsed, ending in a bad ast.
This patch tries to make it better, at least making the ast less bad,
so as to avoid errors in later checks.
* Fix parsing of some operator
It is still very broken, but at least, it does not fail.
Here is the previous error:

```
* Replace some ASSERT_EQUALS with TODO_ASSERT_EQUALS when the actual result is still wrong
* Remove invalid code from simplifyTypedef129
* Properly skip parentheses
I fixed the AST enough to pass testrunner but I don't believe it is
correct.
This code:
void Foo4(int&&b);
has this AST:
( 'void'
|-Foo4
`-&& 'bool'
|-int
`-b 'signed int'
but I don't believe && should have `bool`.
