[StaticAnalyzer] Move inline counter increaser to inlineCall function

[StaticAnalyzer] Move inline counter increaser to inlineCall function

Even though the shouldInlineCall function returns true, it can happen that the
function is not going to be inlined (as it can be seen at line 913 and below).
Moved the bumpNumTimesInlined(D) (the counter increaser) call to the inlineCall
function where it logically belongs.
