Moves some .def files into include/DebugInfo/CodeView.
Aslo remove a 'using namespace' directive from a header in readobj and
update the uses of the endian helper types to compensate.

[resubmit after fixing build bot failures: qualify make_unique and eliminate -Wcovered-switch-default warning.
With the planned size reduction change, the coverage format version is expected to be bumped up. This patch adds necessary support such that backward compatibility can be kept with maximal code sharing. Reading different versions of coverage data just requires instantiating the reader according to the version.
No functional change is intended.

This adds a detailed profile summary in llvm-profdata. The summary is in the
form of one or more triples of the form (P, N, M) which is interpreted as if
we look at the Top-N counts in the profile, their sum accounts for P percentage
of the sum of all counts in the program and the minimum count in the Top-N is M.

This rewrites and expands the existing codeview dumping functionality in
llvm-readobj using techniques similar to those in lib/Object. This defines a
number of new records and enums useful for reading memory mapped codeview
sections in COFF objects.
The dumper is intended as a testing tool for LLVM as it grows more codeview
output capabilities.

The LinkAllPasses.h file is included in several main programs, to force
a large number of passes to be linked in. However, the ForcePassLinking
constructor uses undefined behavior, since it calls member functions on
`nullptr`, e.g.:
((llvm::Function*)nullptr)->viewCFGOnly();
llvm::RGPassManager RGM;
((llvm::RegionPass*)nullptr)->runOnRegion((llvm::Region*)nullptr, RGM);
When the optimization level is -O2 or higher, the code below the first
nullptr dereference is optimized away, and replaced by `ud2` (on x86).
Therefore, the calls after that first dereference are never emitted. In
my case, I noticed there was no call to `llvm::sys::RunningOnValgrind()`!
Replace instances of dereferencing `nullptr` with either objects on the
stack, or regular function calls.

Summary:
Return values can be stored in SGPRs (i32) and VGPRs (f32).
This will be used by functions which expect some bytecode or other binary to
be appended at the end. It allows defining in which registers the return
values will be stored.
v2: don't do this for compute shaders

is < ``2.0``.
Older versions of psutil (e.g. ``1.2.1`` which is the version shipped with
Ubuntu 14.04) use a different API for retrieving the child processes.
To handle this try the new API first and if that fails try the old API.
