This fixes an issue where a namespaced class beginning with "U" or "u"
would yield an invalid arginfo file due to the occurrence of a unicode
escape sequence, causing a compile error.

Closes GH-9154.
@cname currently refers to the constant name in C. However, it is not always a (constant) name, but sometimes a function invocation, so naming it as @cvalue would be more appropriate.
* Support the `#[\AllowDynamicProperties]` attribute in stubs
* Use `#[\AllowDynamicProperties]` attribute in stubs
* Disallow applying both `@strict-properties` and `#[\AllowDynamicProperties]`
This does a compile time transformation of ``iterable`` into ``Traversable|array`` which simplifies some of the LSP variance handling.
The arginfo generation script from stubs is updated to produce a union type when it encounters the type ``iterable``
Extension functions which do not regenerate the arginfo, or write them manually are still supported by mimicking the compile time transformation while registering the function.
Type Reflection is preserved for single ``iterable`` (and ``?iterable``) to produce a ReflectionNamedType with name ``iterable``, however usage of ``iterable`` in union types will be converted to ``array|Traversable``
As described in autoconf-archive upstream [1], from where
`build/ax_gcc_func_attribute.m4` is forked, the old unknown func attr
detection method would throw a false negative anytime an unrelated
warning was raised.
This results in `ax_cv_have_func_attribute_target` being set to `no`
whenever certain compiler Warning flags are switched on. Namely, having
`-Wall` on, which is a default CFLAG for some linux distributions, will
result in
```
warning: ‘bar’ declared ‘static’ but never defined [-Wunused-function]
```
when evaluating support for the `target` function attribute.
With that configuration value set to `no`, the compiled php binaries
will not support x86_64 v3 instructions such as avx2 and sse2, which
should speed up specific tasks ran by PHP.
This issue was originally reported in Ubuntu [2].

Closes GH-8483.
The .gcda files generated by "$(MAKE) PROF_FLAGS=-fprofile-generate all"
should be removed. Otherwise, the profile data in them would be combined
with the profile data of user's workload.Then, they would be used by
"make prof-use" later.
Closes GH-8284.
