Fix AST for brace initialization after decltype() (#3245) 
Currently sub-expressions like decltype(x){} break AST creation for
subsequent tokens in the whole expression. In some cases this triggers
validation checks in validateAst() and analysis on the file stops.
For example, code like this:
    int x = decltype(0){} ? 0 : 1;
currently produces internalAstError.

To fix the issue iscpp11init_impl() was changed to recognize { preceded
by decltype(expr) as a start of C++11 brace initialization expression.

Fixed #9729 (AST broken: lambda with noexcept keyword) (#3243) 
The previous fix for the issue (43b58dbc9e) didn't seem to actually fix
it because it added a check for noexcept without a condition, but when
AST is created noexcept always has a condition due to simplification
from "noexcept" to "noexcept(true)" in Tokenizer::simplifyKeyword().
The issue from the ticket couldn't be reproduced neither on 43b58dbc9e
nor on the previous commit, so it is hard to tell whether the fix was
effective or not.

The issue appeared again after a refactoring of AST code in ac67049661.
Test added with the original fix was unable to catch that because it
used testAst() helper function which skips most simplification steps.

To fix the issue we now check for noexcept with a condition and add a
proper regression test that:
1. Uses tokenizeAndStringify() to ensure that all simplifications are
   performed before AST is created.
2. Parses the code snippet from the ticket, as having "if (cond)" is
   crucial to reproducing the original issue (internalAstError).

Also fix AST creation for lambdas that have both constexpr and mutable
keywords.
