Rikard Falkeborn 794f65bac1 Handle prefixed strings and characters in Token (#1742)

before the tokenizer is called.

Rikard Falkeborn 6a3dd9a185 Handle concatenated string and char literals
This handles concatenated strings and characters from simplecpp.
Previously, L'c' would be preprocessed to the tokens  "L" and "'c'".
cppcheck would then remove the "L" token and set "'c'" to be a wide
character literal. Now, it needs to remove the prefix instead.

When doing this, add handling of utf32 encoded literals (U) and UTF-8
encoded literals (u8).

rikardfalkeborn dc4e7cef88 Run simplifyPlatformTypes on library return types (#1672)
Add a call to simplifyPlatformTypes() in
SymbolDatabase::setValueTypeInTokenList() to simplify return types of
library configured functions. This fixes the FN in #8141. Regression
tests are added, both for the original issue and another FN in the comments.

In order to do that, move simplifyPlatformTypes() to TokenList from Tokenizer.
This is a pure refactoring and does not change any behaviour. The code was
literally copy-pasted from one file to another and in two places
'list.front()' was changed to 'front()'.

When adding the call to simplifyPlatformTypes(), the original type of
v.size() where v is a container is changed from 'size_t' to 'std::size_t'.
Tests are updated accordingly. It can be noted that if v is declared as
'class fred : public std::vector<int> {} v', the original type of 'v.size()'
is still 'size_t' and not 'std::size_t'.

IOBYTE 1faae52d06 Fixed #8960 ("(debug) Unknown type 'x'." with alias in template class alias) (#1643)
* Fixed #8960 ("(debug) Unknown type 'x'." with alias in template class alias)

This commit adds non-template type alias support to the template
simplifier.  Only relatively simple type aliases are supported at this
time. More complex types will be added later.

--debug-warnings will show unsupported type aliases.

Type alias support will be removed from the symbol database in the
future.  Type alias tests have been removed from the symbol database
tests.

* Add the changes.

* Fix codacy warning.

* Fix travis warnings.
