  Log Message:
  -----------
  [Clang] Optimize some `getBeginLoc` implementations (#141058)

The bulk of the changes are in `CallExpr`

We cache Begin/End source locs in the trailing objects, in the space
left by making the offset to the trailing objects static.
We also set a flag to indicate that we are calling an explicit object
member function, further reducing the cost of getBeginLoc.

Fixes #140876
