Subject: [PATCH 054/116] 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.

Subject: [PATCH 072/116] Revert "aarch64: remove CPU features that are
 actually just CPUs"

This reverts commit 6dd514ac8aa3ee2e5c6fd0374469d361ccfce5b9.

This strategy won't work for arm 32-bit; instead need to try to figure
out how to get more bits into the bit set.

Subject: [PATCH 091/116] 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.

Subject: [PATCH 094/116] 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.

Subject: [PATCH 101/116] disable f128 compiler_rt tests failing on windows

These were never working with native CPU features. In this branch,
we fix native CPU features not being enabled on Windows, and regress
f128 language features. In the llvm10 branch, all this is fixed,
and the tests are re-enabled.

Subject: [PATCH 109/116] split IrInstruction into IrInst, IrInstSrc, IrInstGen

This makes it so that less memory is used for IR instructions, as well
as catching bugs when one expected one kind of instruction and received
the other.

Subject: [PATCH 112/116] fix debug info code not being freestanding compatible

in stack tracing code, the idea was to detect the tty settings at the
top of the stack and pass the information down. somewhere along the way
this got changed so that setTtyColor was assuming the global stderr_file
was related to the output stream the stack trace was being printed to.

now, tty_color is changed to tty_config, and it is an enum rather than a
bool, telling how tty colors are expected to be handled. windows is
still incorrectly looking at stderr_file.

Subject: [PATCH 116/116] Unify the two DWARF interpreters

* Let's consolidate the special-cased DWARF interpreter for OSX with the
  general purpose one

* Drop the assumption that all the debug data is contained in a single
  contiguous slice of memory. This is a good news for freestanding
  targets and paves the way for supporting compressed debug sections.
