Rikard Falkeborn 7973fd843c Refactor: Simplify checkSignConversion
The loop only checks astoperand1 and astoperand2. Simplify the condition
to loop over these instead of using a stack. Also, add a testcase for
when astoperand2 is negative.

Rikard Falkeborn 4dbf006dc7 Fix severity of c++14 shifts with too many bits (#2213)
For c++14, shifting a variable with a value larger than or equal to the
number of bits in the variable is undefined. Left-shifting with a value
equal to the number of bits of the variable is implementation defined.

See also trac ticket #9306.
