Remove reflection hacks for primitive typehints

Summary: When updating how primitive typehints worked, some hacks were done to strip
the "HH\" prefix from the output of various refleciton methods. These hacks
shouldn't be needed anymore. This diff removes the hacks and fixes up
ReflectionParameter::getClass() to be aware of the 'num', 'resource',
'mixed', and 'void' typehints.
