Cacheline demote to improve performance (#11101)

Once code is emitted to JIT buffer, hint the hardware to
demote the corresponding cache lines to more distant level
so other CPUs can access them more quickly.
This gets nearly 1% performance gain on our workload.

Use capstone explicitly, drop oprofile (GH 10876) (#10918)

* ext/opcache/config.m4: new --with-opcache-capstone flag.

Until now, libcapstone has been detected "automagically" and used for
JIT disassembly whenever it is available on the system used to compile
PHP. This can have some unintended consequences, however: many users
have capstone installed for some other purpose, and are surprised to
find that PHP breaks when capstone is later uninstalled.

To address this, we have introduced a new --with-opcache-capstone flag
that is disabled by default, and that makes the user's preference
explicit. It is ignored unless the JIT is enabled.

* ext/opcache: drop support for the oprofile JIT profiler.

Recently we have replaced the "automagic" detection of capstone at
build time with a --with-opcache-capstone flag. The detection of
oprofile causes similar problems and would likely have the same
solution; however, it was suggested that we might remove oprofile
altogether. So, this commit removes it:

* Remove the detection bits from ext/opcache/config.m4.
* Drop HAVE_OPROFILE ifdef blocks.
* Delete ext/opcache/jit/zend_jit_oprofile.c.
* Undefine the ZEND_JIT_DEBUG_OPROFILE constant.

Fix module shutdown crash during ZTS JIT shutdown

Commit a21195650e53 fixed a leak by adding a TSRM destructor for the
JIT globals in ZTS mode. In case the main thread shuts down the TSRM, it
will call all the destructors. The JIT globals destructor will be
invoked, but will always access the main thread globals using JIT_G.
This means that instead of freeing the JIT globals in the different
threads, the one in the main thread is freed repeatedly over and over,
crashing PHP. Fix it by always passing the pointer instead of relying on
JIT_G.

Closes GH-10835.

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.

ext/opcache/zend_jit: call TSRM dtor before unloading opcache.so (#10533)

Commit a21195650e53e added a TSRM destructor, but that destructor
will get called by tsrm_shutdown(), which is after opcache.so has
already been unloaded, resulting in a shutdown crash, e.g.:

#0 0x00007fad01737500 in ?? ()
#1 0x000055ac54e723c4 in tsrm_shutdown () at TSRM/TSRM.c:194
#2 0x000055ac54c42180 in main (argc=80, argv=0x55ac57bc14d0) at sapi/cli/php_cli.c:1388

By calling ts_free_id() before opcache.so gets unloaded, we can easily
fix this crash bug.

Delay debug JIT op_array dump until actual JIT-ing

Previously function JIT for the whole script (opcache.jit=1205) dumped
all op_arrays before JIT-ing the first functon. This complicated debugging
of particular JIT-ed function and leaded to usage of opcache.jit=1204.
Now both options should produce similar op_array/disasm interlived
output.
