Fix isInstantiated and isInTemplateInstantiation to not recreate the matchers on each call.

Summary:
Store the result matcher after the first call and reuse it later on.
Recreating the matchers just to use them once incurs in a lot of
unnecessary temporary memory allocations.
This change speeds up our clang-tidy benchmarks by ~2%.
