Fix varId assignment for uses of variables declared in the if condition (#3231)
Variables declared in the if condition (or in C++17 init-statement) are
visible not only in the if body but also in the else body. But logic in
Tokenizer::setVarIdPass1() handled such variables as if they were
declared in the if body.

As the result they were removed from variablesMap by the time the else
block was parsed and their uses in the else block were either given an
incorrect varId from variables in some outer scope or not given a varId
at all.

This then resulted in false positive unreadVariable errors for variables
declared in the if condition (or init-statement) and used only in the
else block.

Simplification from "else if ..." to "else { if ... }" was moved before
setVarId() to simplify detection for ends of blocks in if-else chains.

Fix #9647: Set correct enum value (#2856)
* Tokenize: Set varId for variables in enum

Set varIds in enum values. It was previously disabled in 5119ae84b879fad
to avoid issues with enums named the same as global variables. Take care
to only set varids to variables used to set the value of an enumerator,
not the enumerator itself. This is somewhat complicated by the fact that
at the time this happens, astOperand1(), astOperand2(), astParent() etc
are not set. The current implementation is not perfect, for example in
the code below, y will not have a varid set, but x and z will. This is
deemed sufficient for now.

            int x, y, z;
            enum E { a = f(x, y, z); };

* Fix #9647: Value of enums with variables as init values

C++ allows enum values to be set using constexprs, which cppcheck did
not handle before. To solve this, add a new pass to valueflow to update
enum values after global consts have been processed. In order to do so,
I moved all settings of enum values to valueflow. After setting the enum
values, we need another call to valueFlowNumber() to actually set users
of the enums.

There is still room for improvements, since each pass of
valueFlowGlobalConstVar() and valueFlowEnumValue() only sets variables
that are possible to set directly, and not if setting the value of a
variable allows us to set the value of another. For example

	constexpr int a = 5;
	constexpr int b = a + 5;
	enum E { X = a };
	constexpr E e = X;

Here both b and e will not have their values set, even though cppcheck
should be possible to figure out their values. That's for another PR
though.

This was tested by running test-my-pr.py with 500 packages. The only
difference was one error message in fairy-stockfish_11.1, where cppcheck
now printed the correct size of an array instead of 2147483648 which I
assume is some kind of default value. In that package, using a constexpr
when setting enum values is common, but as mentioned, there was no
change in the number of warnings.

c32a568c1f fix #8965 ("(debug) Executable scope 'x' with unknown function." with rvalue parameter in method) (#2237)
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`.
