Summary:  Compiler stack underflow bug with IF based switch statement

Original Submission:  The stack tracking in the compiler generates a -1 stack
state which is responsible for the maxStack being one less
than the actual value. The behavior is observed only when
a function inside the switch-case uses >2 args . The 
verifier throws a stack underflow bug. The problem was 
traced to cg_stmt.tc:1894

The verifier throws a stack overflow error on executing
the compiled binaries.
