48c7e6c48b std.Target.CpuFeatures is now a struct with both CPU and feature set 
Previously it was a tagged union which was one of:
 * baseline
 * a specific CPU
 * a set of features

Now, it's possible to have a CPU but also modify the CPU's feature set
on top of that. This is closer to what LLVM does.

This is more correct because Zig's notion of CPUs (and LLVM's) is not
exact CPU models. For example "skylake" is not one very specific model;
there are several different pieces of hardware that match "skylake" that
have different feature sets enabled.

cbe9a51518 don't trust llvm's GetHostCPUName 
comment from this commit reproduced here:

I have observed the CPU name reported by LLVM being incorrect. On
the SourceHut build services, LLVM 9.0 reports the CPU as "athlon-xp",
which is a 32-bit CPU, even though the system is 64-bit and the reported
CPU features include, among other things, +64bit.
So the strategy taken here is that we observe both reported CPU, and the
reported CPU features. The features are trusted more; but if the features
match exactly the features of the reported CPU, then we trust the reported CPU.

830e0ba2d2 enable native CPU feature for windows; disable failing tests 
See #508. These can be re-enabled when we upgrade to LLVM 10.

6e6ec3d71d put hack back in to disable windows native cpu features 
See #508. This can be removed when we upgrade to LLVM 10.

35c681b7b1 Fix sentinel mismatch in llvm strings 
Previously, buffers were used with toOwnedSlice() to create c strings
for LLVM cpu/feature strings. However, toOwnedSlice() shrinks the
string memory to the buffer's length, which cuts off the null terminator.
Now toSliceConst() is used instead, and the buffer is not deinited
so that the string memory is not freed.
