Reland 4: [analyzer] NFC: Update test infrastructure to support multiple constraint managers
...
Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

[analyzer] Fix crash when lambda captures a variable-length array.
...
When a C++ lambda captures a variable-length array, it creates a capture
field to store the size of the array. The initialization expression for this
capture is null, which led the analyzer to crash when initializing the field.
To avoid this, use the size expression from the VLA type to determine the
initialization value.

[analyzer] DeadStoresChecker: Treat locals captured by reference in C++ lambdas as escaped.
...
The analyzer currently reports dead store false positives when a local variable
is captured by reference in a C++ lambda.
For example:
int local = 0; auto lambda = [&local]() {
local++;
};
local = 7; // False Positive: Value stored to 'local' is never read
lambda();
In this case, the assignment setting `local` to 7 is not a dead store because
the called lambda will later read that assigned value.
This commit silences this source of false positives by treating locals captured
by reference in C++ lambdas as escaped, similarly to how the DeadStoresChecker
deals with locals whose address is taken.

[analyzer] Refer to capture field to determine if capture is reference.
...
The analyzer incorrectly treats captures as references if either the original
captured variable is a reference or the variable is captured by reference.
This causes the analyzer to crash when capturing a reference type by copy
(PR24914). Fix this by refering solely to the capture field to determine when a
DeclRefExpr for a lambda capture should be treated as a reference type.
