Remove x86 bit test optimization

This is undefined behavior and we cannot rely on it. Additionally it
breaks builds using undefined behavior sanitizers.

Fix clang compilation

By usage of -fmodules, all the intrinsic items are loaded automatically.
The headers included come however from Visual Studio, thus bringing some
conflicting declarations. On the other hand, -fmodules is needed to
mitigate linking issues with clang in VS compatibility mode.

Remove unused Git attributes ident

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

If the target attribute is available, attach it explicitly

The ifunc attribute might be not available as it is binary format
dependent.

Revoke the gcc only restriction

clang at least 5.0 supports GNU style attributes and intrinsic macros.
In general, compilers claiming this functionality should know, what
they do.

fix build with older gccs: label attributes are only available with gcc 5+

Prefer "GNU asm goto" to __builtin_saddl_overflow() for overflow detection. This allows generation of significantly better code.

Enable and fix printf() format warnings

Add _unchecked() variants of zend_spprintf and zend_strpprintf for
cases where we specifically want to disable these checks, such as
use of %H.
