compiled using non-GCC compilers.
This included adding an initialization to a variable that looks(!)
like it can reach a use before being initialized (b/c we turned
JERRY_UNREACHABLE into a nop) -- an example:
int foo;
switch (value_can_only_be_one_or_two)
case 1:
case 2:
foo = 5;
default:
JERRY_UNREACHABLE();
x = foo +1;
...the compiler assumes that the path can go through the default case,
which leaves the value of foo undefined.
