4a9485f830 LibJS: Fix impossible member access for negative integers 
The PropertyName class able to match a number or an array can only
accept positive numerical values. However, the computed_property_name
method sometimes returned negative values.

This commit also adds a basic object access test case.

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()

30ba2c7cec LibJS: Simplify Math-constants.js test 
By borrowing an "expect close" function from LibM/TestMath.cpp, we can
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

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.

Address the FIXME in MathObject::max to handle an arbitrary
number of arguments. Also adding a test case to verify the
behavior of Math.max() while I'm here.

5e40aa182b LibJS: Support VariableDeclaration with multiple declarators 
This patch adds support in the parser and interpreter for this:

    var a = 1, b = 2, c = a + b;

VariableDeclaration is now a sequence of VariableDeclarators. :^)

a58640ce6b LibJS: Parse binary bitwise operators 
The Lexer and AST already have all the functionality required in place,
so this is just updating Parser::match_secondary_expression() and
Parser::parse_expression() to handle TokenType::{Ampersand,Pipe,Caret},
as well as adding some tests.

99aab4470a LibJS: Object::put() shouldn't create own properties on prototype chain 
Unless there is a setter present on the prototype chain, put() should
only set own properties on the object itself.
