zend_compiler, ...: use `uint8_t` instead of `zend_uchar` (#10621)

`zend_uchar` suggests that the value is an ASCII character, but here,
it's about very small integers. This is misleading, so let's use a
C99 integer instead.

On all architectures currently supported by PHP, `zend_uchar` and
`uint8_t` are identical. This change is only about code readability.

Remove JMPZNZ opcode

While JMPZNZ can avoid execution of a separate JMP opcode in some
cases, it also prevents smart branch optimization, so creating
JMPZNZ may actually have a negative effect. It also adds additional
complexity for optimizations.

Drop JMPZNZ in favor of JMPZ+JMP or JMPNZ+JMP.

Closes GH-7857.

The never type can be used to indicate that a function never
