This patch disables automatic detection of module code, and instead
requires the user to explicitly specify whether to parse a source
as a module or as a script.
To achieve this the jerry_parse API function now takes a new option
which signals that the source should be parsed as a module.

- `finite` is not C99 but a BSD fp classification function, so it
is removed.
- The standard specifies that `isnan` is a macro (just like
`isfinite` and `isinf`), so the `isnan` function implementation
is removed.
- `isfinite` incorrectly classified NAN as finite, which is fixed.
- `isinf` returned 1 for negative infinity. This is not a bug
according to the standard, but is not aligned with recent glibc,
which returns -1. This is changed to simplify testing.
- Added test cases for `isfinite` and `isinf` to the unit test of
jerry-math.
- Added a new pass to unittests to ensure that jerry-math is
tested.

Currently, ecma_op_get_prototype_from_constructor may return NULL
and the function didn't raise that exception.
Also optimize multiple assignment of prototype_obj_p and
multiple access of JERRY_CONTEXT (current_new_target) out.
This fixes https://github.com/jerryscript-project/jerryscript/issues/4463

can not be executed properly.

After the introduction of the Proxy builtin object there was
a possibility to traverse the prototype chain with an invalid object.
The prototype was freed before it's data/properties were queried resulting
in accessing invalid information.
By forcing the allocator to always do a gc (`--mem-stres-test=on` build option)
it was possible to trigger the issue without complicated tests.
New internal method:
* `ecma_op_object_get_prototype_of` which always returns the prototype
of an object and the return value must be freed (if it is valid).
Updated prototype chain traversing in:
* `jerry_object_get_property_names`
* `ecma_builtin_object_prototype_lookup_getter_setter`
* `ecma_op_function_has_instance`
* `ecma_op_function_get_super_constructor`
* `ecma_op_object_is_prototype_of`
* `ecma_op_object_enumerate`
Removed method `ecma_proxy_object_prototype_to_cp`

When the mem-stress-test is enabled for the objects foreach unittest
the object counting is off by one. This was due to incorrect assumption
on when the gc is triggered.

Normally, it is more usual and safe to use a toolchain's native
math library. Especially, if multiple components of a project use
math functions, in which case all components should be linked
against the same libm.
The libjerry-math can be used, of course, but as it needs extra
care and consideration, it should be opt-in.

When shifting a negative BigInt value if the
shift count is very "big" the result should be -1.
eg.:
```
(-2n >> (2n*32n)) === -1n
```
Note: the `-2n >> (2n*31n)` already returned `-1n` prior this change.

Proxy flags (IsCallable, IsConstructor) can't be stored on the
property list compressed pointer. As adding a Proxy to a WeakSet
would add a property to the Proxy object causing failures down the line.
The prototype internal "slot" can be used to store there flags as
it is not used in case of Proxies (as per standard).
