Add support for -march=sandybridge 
HHVM's been building with this (or equivalent predecessor patches); it
gets us a 20x speedup on real-world workloads, at the cost of slightly
worse compatibility.

This doesn't change the default, just makes it available as an explicit
choice.

Make Hardware.oldest_cpu depend on architecture 
Starting with Xcode 12 Beta 2, builds that used to work on Apple Silicon
now break due to `Hardware#oldest_cpu` returning `:nehalem` [1].

This commit is the first in a series of improvements to
`Hardware#oldest_cpu`. It resolves the Xcode 12 Beta 2 issue for now.

version: add CPU tests. 
Add a new API inspired by discussion in
https://github.com/Homebrew/homebrew-core/pull/36435 to query if a given
CPU option is supported by a version of macOS.

hardware: no special penryn CFLAGS. 
These are the same as `core2` (at least for `gcc`).

Fixes #5502.

ddb576b582 Add support for testing generic OS. 
If the environment variable HOMEBREW_TEST_GENERIC_OS is set ensure that
neither Mac nor Linux-specific code is loaded. This allows easier
testing of cross-platform code on OS X and will make it easier to port
Homebrew to platforms other than OS X and Linux.

* CPU functions now exist in Hardware::CPU
* Added compatibility functions in compat/hardware_compat.rb
* Names are less specific to Mac hardware, e.g. CPU.family instead of
  Hardware.intel_family
* Hardware::CPU.family works for both Intel and PowerPC
* New helper methods on CPU, like .sse4? and .altivec?

ca71c038a1 Cache Hardware.is_64_bit? 
IO#popen is called for each call to Hardware.is_64_bit?; this becomes
costly when it is repeatedly invoked. Luckily it is an invariant, so we
can store it in a class variable.

False is a valid value for this method, so the usual ||= idiom is not
applicable.
