Replace undefined shift operations by multiplications
...
Shift operations are undefined for negative numbers, but at least on
Intel they return the same value as a multiplication with 2 ^ shift value.
This fixes runtime errors reported by sanitizers and OSS-Fuzz:
intmatcher.cpp:821:59: runtime error: left shift of negative value -14
intmatcher.cpp:823:75: runtime error: left shift of negative value -512
intmatcher.cpp:820:50: runtime error: left shift of negative value -80
