Fixes#4. This is based on #115 with a few modifications:
- Removed use of __builtin_cpu_supports since it relies on cpuid and doesn't improve on the current situation,
- Added detection for all of sse, sse2, sse3, ssse3, sse4_1 and sse4_2,
- Added tests for Atom, Nehalem, and P3 processors,
Thx to @gadoofou87 for providing the original PR.
It also removes the need for #92
* Fix SSE detection on non-AVX CPUs

Fixes#128
This adds the following features: dcpodp, sve2, sveaes, svepmull,
svebitperm, svesha3, svesm4, flagm2, frint, svei8mm, svef32mm,
svef64mm, svebf16, i8mm, bf16, dgh and rng.
With these, all features used by Linux 5.8 on AArch64 is supported.
Fixes#126
* Add support for leaf4 on Intel's x86 arch
* Update cpuinfo_x86.h
* Fix typo
* Force compiler to use C99
* Add Intel x86 leaf2 support
* Fixes after review
* Fix review comments
* First implementation of ndk_compat
* Restrict building of linux_based_hardware_detection to UNIX
* Fix variable declaration and printf formatting
* Restrict ndk compat to UNIX style systems
* Restrict cpu_mask index to 32
* Fix values display in ndk-compat-test
* Addressing comments
It seems that ' : 1' alignments cause signed integers to be either -1 or 0. While -1 is true and 0 is false reverse might not be always correct when true is defined 1.
Maybe change feature variables to bool ?
Some PowerPC machines can operate in a mode that appears different
to a process than the actual hardware. AT_PLATFORM indicates the
supported instruction set and AT_BASE_PLATFORM indicates the
actual microarchitecture of the hardware.

getauxval() returns an unsigned long which can be defined to be
more than 32 bits so don't force the result into a uint32_t.
