2c70581338 Fix T_NUM_STRING negation 
T_NUM_STRING follows the rules of symtable numeric string
conversion. If the offset isn't an integer under those rules, it
is treated as a string. This should apply to negated T_NUM_STRINGs
as well.

8754b191f7 Fix "already in use" check inconsistencies/bugs 
This fixes the following issues:
 * "use function" and "use const" inside namespaced code were checking
   for conflicts against class imports. Now they always check against
   the correct symbol type.
 * Symbol conflicts are now always checked within a single file only.
   Previously class uses inside namespaced code were checked globally.
   This behavior is illegal because symbols from other files are not
   visible if opcache is used, resulting in behavioral discrepancies.
   Additionally this made the presence/absence of symbol errors dependent
   on autoloading order, which is volatile.
 * The "single file" restriction is now enforced by collecting defined
   symbols inside a separate hash table. Previously it was enforced
   (for the non-namespaced case) by comparing the filename of the
   symbol declaration. However this is inaccurate if the same filename
   is used multiple times, such as may happen if eval() is used.
 * Additionally the previous approach relies on symbols being registered
   at compile-time, which is not the case for late-bound classes, which
   makes the behavior dependent on class declaration order, as well as
   opcache (which may cause delayed early-binding).
 * Lastly, conflicts are now consistently checked for conditionally
   defined symbols. Previously only declaration-after-use conflicts were
   checked in this case. Now use-after-declaration conflicts are
   detected as well.
