Tyson Andre df0fa5b178 Clean up remaining opcodes for foreach([] as $x) 
Previously, two useless FE_RESET_R and FE_FREE would be left over whether the empty array
was from a literal, a variable, or a class constant.

This doesn't pick up the RESET_RW case due to a weakness in our "may throw"
modeling. (for foreach by reference).

Nikita Popov 3c68f38fda Restrict allowed usages of $GLOBALS 
This restricts allowed usage of $GLOBALS, with the effect that
plain PHP arrays can no longer contain INDIRECT elements.

Ayesh Karunaratne 724e241c9d JIT: Update invalid opcache.jit INI value message to include "tracing" and "function" values 
`opcache.jit` accepts `tracing` and `function` as aliases, but they were not mentioned in the start-up INI warning message.
This updates the error message to include all possible values.

  Only replace IN_ARRAY result type for JMPZ/JMPNZ
 2020-11-30 11:19:13 +01:00
Nikita Popov fdb05b92bf Only replace IN_ARRAY result type for JMPZ/JMPNZ 
Replacing the result type in the general case is dangerous,
because not all opcodes support both VAR and TMP. One common case
is the in_array() result being passed to SEND_VAR, which would
have to be changed to SEND_VAL.

Rather than complicating this logic, reduce the scope to only
doing the type replacement for JMPZ and JMPNZ. The only reason
we're doing this in the first place is to enable the smart branch
optimization, so we can limit it to the relevant opcodes. Replacing
the result type may be marginally useful in other cases as well
(as it may avoid reference checks), but not worth the bother.
