9aaf19f4de LibJS: Do a garbage collection every N allocations (N=10'000) 
To prevent the heap from growing infinitely large, we now do a full GC
every 10'000 allocations. :^)

1d6c8724b9 LibJS: Fix some tests for Math.min() 
In some of the tests in Math.min.js, we were testing Math.max() instead
of Math.min()

67f7763ab9 LibJS: Object needs to protect values in its storage 
Otherwise the garbage collector will eat them way too soon! This made
it impossible to use "js -g" without crashing.

6e7713a5f4 LibJS: Remove unnecessary malloc+free in AssignmentExpression::execute 
We were creating a temporary AK::Function for no good reason, and this
was dominating profiles. Reorganize the code so it's not necessary.

LibJS: Fix do..while parsing by consuming parentheses explicitly (#1652) 
Before this patch the parser accepted conditions without enclosing
parentheses (like: .."while number < 9").

30ba2c7cec LibJS: Simplify Math-constants.js test

make this a lot simpler. Also the parser now understands decimals!

bc40908d32 LibJS: Use the native assert() implementation now avaiable in 'js -t' 
Switch the LibJS test suite to use the native assert implementation
surfaced inside the js repl when it's launched in test mode.

1e67efc5c1 Lagom: Add clang address/memory/undefined-behavior analyzer support 
Adding the ability to turn on Clang analyzer support in the Lagom build.
Right now the following are working warning free on the LibJS test suite:

 -DENABLE_MEMORY_SANITIZER:BOOL=ON

 -DENABLE_ADDRESS_SANITIZER:BOOL=ON

The following analyzer produces errors when running the LibJS test suite:

 -DENABLE_UNDEFINED_SANITIZER:BOOL=ON

dd112421b4 LibJS: Plumb line and column information through Lexer / Parser 
While debugging test failures, it's pretty frustrating to have to go do
printf debugging to figure out what test is failing right now. While
watching your JS Raytracer stream it seemed like this was pretty
furstrating as well. So I wanted to start working on improving the
diagnostics here.

In the future I hope we can eventually be able to plumb the info down
to the Error classes so any thrown exceptions will contain enough
metadata to know where they came from.

1d468ed6d3 AK: Stop allowing implicit downcast with RefPtr and NonnullRefPtr 
We were allowing this dangerous kind of thing:

RefPtr<Base> base;
RefPtr<Derived> derived = base;

This patch changes the {Nonnull,}RefPtr constructors so this is no
longer possible.

To downcast one of these pointers, there is now static_ptr_cast<T>:

RefPtr<Derived> derived = static_ptr_cast<Derived>(base);

Fixing this exposed a ton of cowboy-downcasts in various places,
which we're now forced to fix. :^)

240a5b5fd7 LibJS: Add support for Math.ceil() and Math.trunc() 
Introduce support for the both of these Math methods.
Math.trunc is implemented in terms of Math.ceil or Math.floor
based on the input value. Added tests as well.

b8cef3a2d3 LibJS: Add support for floating point modulous 
This change implements floating point mod based on the algorithm
used in LibM's fmod() implementation. To avoid taking a dependency
on LibM from LibJS I reimplemented the formula in LibJS.

I've incuded some of the example MDM test cases as well.
This surfaced and issue handling NaN which I've fixed as well.

The last computed value is now available in Interpreter::last_value()
instead, where the REPL can pick it up.
