Some test updates, parameter naming standardization, and the basic ValueError arg number fix. This doesn't solve the method/function argument issue, but is a step forward.

Sorry for the delay, had some technical issues: but for the mysqli extension I defined a new macro:

#define ERROR_ARG_POS(arg_num) (getThis() ? (arg_num-1) : (arg_num))

And you use the ZPP arg value as the arg_num and that handles the OO/procedural API differences.

#define ERROR_ARG_POS(arg_num) (getThis() ? (arg_num-1) : (arg_num))

Thank you. I guess it does make sense to leave it to the caller to decide what to pass to the zend layer.

I've pushed the change.

Great :D do you want me to merge and squash this and update this PR back on php-src?

Can you merge 6116 to PHP master? I don't think there is anything outstanding on it. I will review other potential warning promotions when I get more time.

Thanks for all your work.

Fix DCE of FREE of COALESCE
0826a54 
When encountering the following SSA graph:

    BB1:
    #2.T1 [string] = COALESCE #1.CV0($str) [null, string] BB2

    BB2:
    #5.T1 [string] = QM_ASSIGN string("")

    BB3:
    #7.X1 [string] = Phi(#2.X1 [string], #5.X1 [string])
    FREE #7.T1 [string]

We would currently determine that #7, #5 are dead, and eliminate
the FREE and QM_ASSIGN. However, we cannot eliminate #2, as
COALESCE is also responsible for control flow.

Fix this my marking all non-CV phis as live to start with. This
can be relaxed to check the kind of the source instruction, but
I couldn't immediately come up with a case where it would be
useful.

Support failed JIT test case: send_ref_001.phpt
f11b440 
Part of generated opcodes for $foo are:

  ...
  BB1:
  0002 INIT_FCALL 1 96 string("foo")
  0003 #5.V1 [rcn, object (instanceof A)] = FETCH_THIS
  0004 SEND_REF #5.V1 [rcn, object (instanceof A)] 1
  0005 DO_UCALL

Updates in functions zend_jit_fetch_this() and zend_jit_load_this() are
made to support FETCH_THIS opcode.

One new path is covered in function zend_jit_send_ref()  by SEND_REF
opcode.

even without sanitizers, it is reproducible but with the following

```
<?php
$g = gmp_init(256);
var_dump(gmp_pow($g, PHP_INT_MAX));
```

we get this
