This fixes HashMap where a key or part of a key is a floating point
number. To fix this the following has been done:
* HashMap now takes an extra template argument Comparator. This class
gets used to compare keys. The default Comperator now works correctly
for common types and floating point numbets.
* Variant implements ::hash_compare() now. This function implements
nan-safe comparison for all types with components that contain floating
point numbers.
* Variant now has a VariantComparator which uses Variant::hash_compare()
safely compare floating point components of variant's types.
* The hash functions for floating point numbers will now normalize NaN
values so that all floating point numbers that are NaN hash to the same
value.
C++ module writers that want to use HashMap internally in their modules
can now also safeguard against this crash by defining their on
Comperator class that safely compares their types.
GDScript users, or writers of modules that don't use HashMap internally
in their modules don't need to do anything.
This fixes#7354 and fixes#6947.
The code would get a pointer to the beginning of the call_args by using
operator[] at the stack Vector. This does bound checking. When there are
no call_args this bound check fails and the error mentioned in #7796
gets triggered.
This bound check is actually not necessary as call_args just gets set to
NULL and never dereferenced. This new code will just unconditionally set
the pointer to the place where the call_args are if there are any. There
is no NULL check for call_args anywhere so this is safe.
Fixes#7796
problem was a segmentation fault caused by trying to access Vector constants[0] which isn't there if op->arguments.size() is not bigger than one.
- the changed OR condition didn't make sense (always true), should be AND
- changes the "constant" variable to be false per default and gets set to true when there is actually something pushed to "constants"
clang-format does not handle that well *at all*.
For the reference, found the relevant pieces of code with:

Made sure files in core/ and tools/ have a proper Godot license header
when written by us. Also renamed aabb.{cpp,h} and object_type_db.{cpp,h}
to rect3.{cpp,h} and class_db.{cpp,h} respectively.
Also added a proper header to core/io/base64.{c,h} after clarifying
the licensing with the original author (public domain).
