0ee360982d improved test mode -t 
The test mode do no longer open a file `/dev/null` nor write anything to output.

This is supposed to be more efficient than writing to `/dev/null`,
and more universal too : the previous method was failing on Windows.

482b84f07b Make detection of symbolic links more consistent 
While fixing the detection of symbolic links on OpenBSD I noticed
inconsistent behaviour:

$ echo hello > hello
$ ln -s hello world
$ zstd hello world
Warning : world is a symbolic link, ignoring
hello                :316.67%   (     6 =>     19 bytes, hello.zst
$ ls *.zst
hello.zst
$ zstd world
world                :316.67%   (     6 =>     19 bytes, world.zst)
$ ls *.zst
hello.zst world.zst

Print a stack trace on unexpected term signal (e.g. SIGABRT) 
For OSX and Linux, add a signal handler to SIGABRT, SGIFPE, SIGILL,
SIGSEGV, and SIGBUS. When the program terminates unexpectedly the
handler will print the current stack to the terminal to help determine
the location of the failure.

On OSX the output will look like:

```
Stack trace:
4   zstd                                0x000000010927ed96 main + 16886
5   libdyld.dylib                       0x00007fff767d1015 start + 1
6   ???                                 0x0000000000000001 0x0 + 1
```

On Linux the output will look like:

```
Stack trace:
./zstd() [0x4b8e1b]
./zstd() [0x4b928a]
./zstd() [0x403dc2]
/lib64/libc.so.6(__libc_start_main+0xf5) [0x7f5e0fbb0445]
./zstd() [0x405754]
```

As is, the code does not function on WIN32.

* Add FASTCOVER_MEMMULT

* Minor fix

* Update benchmarking result
