netbsd-arm needs the same override to the alignment function as

Add basic support for IBM Z (s390x) CPU feature (known as
'facilities') detection.
Note that some of these features are mandatory when using the Go
compiler (for example, ldisp and eimm) but aren't mandatory when
using gccgo.
Cryptographic function detection is not yet implemented for
gccgo.

On Android /proc/self/auxv is not readable, leading to a panic in init.
Instead of panic'ing in this case, introduce the Initialized global bool
to report whether the CPU features were initialized i.e. /proc/self/auxv
was successfullly read.

This change adds a go.mod file to this repo, following the
requirements stated in bcmills's comment here:
https://golang.org/issue/28136#issuecomment-462971974. It's
important to note that we will not be
adding versions to the repo for now.
This change does not add a go.sum because this repo has no dependencies.
The change was generated by running "go mod init" and "go mod tidy" using Go
1.11.5 in the top-level directory of the repository.

The stat structure on linux/mips64x differ between C library and the kernel,
as described in the stat(2) man page.
Fstat, Lstat and Stat on linux/mips64x already converts the stat structure
using a fillStat_t function, very similar to __xstat_conv in GLIBC.
Doing the same for Fstatat before calling SYS_NEWFSTATAT fixes the
"Fstatat: returned stat does not match Stat/Lstat" error in TestFstatat.
