Fix profiler unicity when several ones are registered
Closes#2627, closes#2643, alternative to #2645
What happens is that both Twig and Symfony register a Twig profiler. Unfortunately, the current code does assign the same variable for both profiler, which means that trying to close it twice does not work.

Switch the PHP ext jobs to a whitelist rather than a blacklist
Any new PHP version added in the future will be a PHP 7.x one, not a 5.x one, and so should not have a job for the extension.
the whitelist is already shorter than the blacklist today (3 whitelisted vs 4 blacklisted before, as PHP 5.3 is already handled separately due to precise anyway)

Improve performance by inlining constants
This one was suggested by @nicolas-grekas and it is similar to what we've done for the Symfony container. That improves performance **a lot**. Combined with my previous pull request, method calls are now twice as fast as the current stable 2.x release.

Optimize the performance of the dot operator
This is an alternative to #2359 and #2361, and closes#2326.
Basically, we don't need to call `hasExtension()` at runtime for the sandbox check when calling the dot operator as we know if it's enabled at compile time (the cache hash depends on enables extensions).
My benchmarks shows a *huge* performance improvement (**around 20%**) by doing so (especially when not using the sandbox, which is almost always the case).
