Length parameter to substr() behaves differently for PHP8+. It recognizes null as if no value was provided at all. Updated the documentation to reflect this.

This patch clarifies the usage of the four JIT tunable options -
jit_hot_{loop,func,return,side_exit} - in PHP manual which end users
should be aware of before they start to tune these options.
1. Valid value range
2. Default value will be used in case beyond valid range
3. Special case of zero value
The patch was verified on my machine with phd local website.

As a new bird to PHP interpreter, I tried to set jit_bisect_limit
with jit=tracing in order to debug/probe PHP JIT feature, but
failed to hit my breakpoint and hence got confused.
I found that jit_bisect_limit only works under special JIT trigger
mode like 0: on script load, or 1: on first execution, after heavily
reading source code and trial-and-error experiments.
So, I would like to clarify the usage in PHP manual.
Hopefully, this can save time cost and reduce confusion of new PHP
interpreter developers.
The patch is verified on my local machine with phd build and the
web content and link looks good.

These classes are already documented elsewhere. toPHP() is rarely used directly and the types themselves are uncommon, so there is little need to call them out here.
I tried to tell JIT to compile every loops and functions
by setting both opcache.jit_hot_loop and opcache.jit_hot_functions
to 0, but failed to get expected result.
After having read the source code and simple experiments, I found
that setting these two options to 0 will actually disable JIT to
compile any iterations and calls.
So I would like to add clarifications for this behavior in PHP manual.
