Rikard Falkeborn 1fcbd696be Token::ConcatStr(): Handle mixed string literals (#2337)
Improve handling of adjacent string literals of different types.

Example of adjacent string literals: "ab" L"cd".

In C89, C++98 and C++03, this is undefined. As of C99 and C++11, this is
well defined and the two string literals are concatenated to L"abcd".
C11 and C++11 introduces the utf16, utf32 and (C++ only) utf8 string
types. Concatenating any of these with a regular c-string works exactely
as the wide string example above. The result of having two adjacent
string literals with different prefix is implementation defined, unless
one is an UTF-8 string literal and the other is a wide string literal.
In this case the behaviour is undefined.

Ignore the undefined and ill-formed programs (this behaviour is unchanged)
and make sure that concatenating a plain c string literal with a prefixed
one works correct (in C99 and C++11 and later versions). It also makes the
behaviour consistent since previously, "ab" L"cd" would result in "abcd"
while L"ab" "cd" would result in L"abcd".

It also means the somewhat awkward updatePropertiesConcatStr() test can
be removed since the added tests would not work if update_properties()
was not called in concatStr().

Since the prefix is stored in the token, testing the type of the string
is not relevant in TestSimplifyTokens. It is tested extensively in
TestToken::stringTypes().

Georgy Komarov c207828a11 misra.py: Fix large memory usage with suppressions (#2321)
* misra.py: Fix large memory usage with suppressions

Don't save whole lxml locations when collecting rules suppressions
statistics. This fixes the problem with large memory usage when
some rules are suppressed.

See issue description:

* don't override 'file' builtin

Georgy Komarov ff61d8e370 misra.py: Skip execution for globally suppressed checks (#2301)
These changes will improve misra.py execution time in the
case where we use globally suppressed checks. For example, when using
single MISRA rule and suppress others, we could get about twice the
execution speed, since most of `MisraChecker' class methods will not
be started at all.
