Improve performance of InterfaceValidator

[lbajsarowicz]

Description (*)

According to the fact that we have:

• 1455 after plugins
• 819 before plugins
• 246 around plugins

in Magento, I changed the order of conditions in Magento Interface Validator that is executed every single time when plugins are mentioned, to improve the logic performance.

Only by changing the order of conditions, we get in average 15% of performance improvement:

Benchmarking method (pseudocode)

for ($i = 0; $i < 1455000; $i++) {
    getMethodType('afterNothingMatters');
}

for ($i = 0; $i < 819000; $i++) {
    getMethodType('beforeNothingMatters');
}

for ($i = 0; $i < 246000; $i++) {
    getMethodType('aroundNothingMatters');
}

for ($i = 0; $i < 1000000; $i++) {
    getMethodType('actuallyNothingMatters');
}

Additionally, replaced Elvis (?:) operator with null coalescing operator (??) which does not juggle types during comparison.

On line 73 you can see that I moved === null comparison before the other comparison because it's cheaper to compare to null than execute additional class method.

Replaced substr comparison with strpos which during my benchmark improved the performance slightly:

After all my changes, the Class performs about 21% faster

How do you...?

@lbajsarowicz what if you use if confition with continue instead of switch when comparing $methodType ?

Replaced in both occurrences. Still keeping the number of occurrences in mind.

The refactored logic is already covered by corresponding test \Magento\Framework\Interception\Test\Unit\Code\InterfaceValidatorTest.
