1ffa48cc61 Add branch prediction hint for mi_option_get 
mi_option_get is called frequently in stress tests, and the patch adds
extra hint to the compiler to emit instructions that will cause branch
prediction to favour the "likely" side of a jump instruction.

8c2f52dee8
Suppressed the new GCC 9 -Wmissing-attributes warnings 
With the new release of the GCC 9 compiler the operation of -Wmissing-attributes warnings has also been extended to aliases: this causes a warnings if the alias has less attributes than its target.

This warnings does not actually indicate a problem in the mimalloc code and you could safely ignore it by adding "-Wno-missing-attributes" to the CFLAGS, however I was not going to use a "hack" to hide the warning when compiling alloc-override .c

So this patch solves the problem simply by using an attribute (present only in GCC> = 9) that copies the attributes of another function, since this attribute is exclusive only for GCC 9 (or later) I had to use a simple precompiler instruction to add the "copy" attribute only with GCC 9.

329a494783 Make forwarding macros friendly to indentation or style checkers 
Indention programs such as clang-format usually rely on the occurrence
of statement terminator, otherwise they are likely confused. The revised
forwarding macros do not contain semicolons character, which is friendly
to indentation or style checkers.

256eb97849 Avoid unnecessary symbol exposure with ELF-based systems 
GCC's default visibility is "public" but can be changed to
"hidden" with the argument "-fvisibility=hidden".

Tested with x86_64 / Ubuntu Linux 18.04 LTS:

[before]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
142

[after]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
93

This patch does not change the build on macOS.

855e2f0d89 Use clock_gettime() instead of timespec_get() 
clock_gettime(CLOCK_REALTIME, &ts) is equivalent to timespec_get(&ts,
TIME_UTC) in C11.

It has the advantage that avoids the following building error when building
with macOS:

a667971cbf Apple rebrands "OS X" as "macOS" 
In 2012, with the release of OS X 10.8 Mountain Lion, the name of the
system was shortened from Mac OS X to OS X. In 2016, with the release
of macOS 10.12 Sierra, the name was changed from OS X to macOS to
streamline it with the branding of Apple's other primary operating
systems: iOS, watchOS, and tvOS.
