Working commit for constant scalar expressions (with constants).
Tests will follow.
Fixed mem leaks, added tests and ternary operator
Fatal error about self referencing constants fixed
converted several switches to ifs and made more opcache friendly
Whitespace fix
Added a few more operators
Removed operations on constant arrays.
They make no sense as constants are not allowed to be arrays.
And as just properties are allowed to; no problem, we still don't
need operations on any constant array.
Merge branch 'const_scalar_exprs' of github.com:bwoebi/php-src into const_scalar_exprs
