I noticed that directorty structure of hphp/system was a bit scattered, so
I consolidated things to reduce the total number of folders and to put
related things together with each other.
This diff moves the contents of "hphp/system/classes_hhvm" into
"hphp/system", it moves the contents of "hphp/system/lib" into
"hphp/system", moves "hphp/idl" to "hphp/system/idl", and moves the
contents of "hphp/system/globals" into "hphp/system/idl".
Array and Variant don't need to accept double for array keys,
since they can only be int or string anyways. The only place
we called those methods was in test_cpp_base.cpp anyway.
This is the first results from profiling callsites of
StringData::initLiteral. This diff converts a handful more
string literals to StaticString, removes overloaded Variant
comparison operators (operator==, etc), and avoids
constructing new strings in a few cases in tvCastToString
and tvCastToStringInPlace.
I've been linking people to the README in this directory, but it is hard to see with all these files in here. What do people think about it moving a subdirectory? I don't love the name.
