Takuya Shimizu b3469ce6f8 [clang][Analysis] Handle && and || against variable and its negation as tautology ...

This patch introduces a new warning flag -Wtautological-negation-compare grouped in -Wtautological-compare that warns on the use of && or || operators against a variable and its negation.
e.g. x || !x and !x && x
This also makes the -Winfinite-recursion diagnose more cases.
