Linearizer outputs incorrect code if a variable is initialized inside a branch #9

An example of this issue is in:

https://github.com/dibyendumajumdar/dmr_c/blob/master/tests/bugs/simplifybug.c

The workaround is to disable sparse simplifications. In dmr_C this is achieved by making simplification optional - it is triggered only if -O1 option is supplied.
