Fixed assertion failure
Basic Block in function 'main' does not have terminator!
label %land.end
caused by premature setting of CodeGenIP upon entry to
emitTargetDataCalls, where subsequent evaluation of logical expression
created new basic blocks, leaving CodeGenIP pointing to the wrong basic
block. CodeGenIP is now set near the end of the function, just prior to
generating a comparison of the logical expression result (from the if
clause) which uses CodeGenIP to insert new IR.
