Gabor Bencze 3373e84539 [clang-tidy] Add bugprone-suspicious-memory-comparison check 
The check warns on suspicious calls to `memcmp`.
It currently checks for comparing types that do not have
unique object representations or are non-standard-layout.
Based on
  https://wiki.sei.cmu.edu/confluence/display/c/EXP42-C.+Do+not+compare+padding+data
  https://wiki.sei.cmu.edu/confluence/display/c/FLP37-C.+Do+not+use+object+representations+to+compare+floating-point+values
and part of
  https://wiki.sei.cmu.edu/confluence/display/cplusplus/OOP57-CPP.+Prefer+special+member+functions+and+overloaded+operators+to+C+Standard+Library+functions
Add alias `cert-exp42-c` and `cert-flp37-c`.

Some tests are currently failing at head, the check depends on D89649.
