This commit augments spv.CopyMemory's implementation to support 2 memory
access operands. Hence, more closely following the spec. The following
changes are introduces:
- Customize logic for spv.CopyMemory serialization and deserialization.
- Add 2 additional attributes for source memory access operand.

As requested, these tests check for specific debug locs on the output of the
legalizer. The only one that I couldn't write was for moreElementsVector, which
AFAICT we don't trigger on AArch64.
PassInfoMixin should be used for all NPM passes, rater than a custom
`name()`.
This caused ambiguous references in LegacyPassManager.cpp, so had to
remove "using namespace llvm::legacy" and move some things around.
The passes had to be moved to the llvm namespace, or else they would get
printed as "(anonymous namespace)::FooPass".

Fix fronted shared library builds by eliminating dependences of
the parser on other component libraries, moving some code around that
wasn't in the right library, and making some dependences
explicit in the CMakeLists.txt files. The lowering library
does not yet build as a shared library due to some undefined
names.

Summary:
When a program unit creates a generic based on one defined in a module, the
function `CopyFrom()` is called to create the `GenericDetails`. This function
copied the `specificProcs_` but failed to copy the `bindingNames_`. If the
function `CheckGeneric()` then gets called, it tries to index into the empty
binding names and causes the crash.
I fixed this by adding code to `CopyFrom()` to copy the binding names.
I also added a test that causes the crash.

Summary:
-debug-info-kind=constructor reduces the amount of class debug info that
is emitted; this patch switches to using this as the default.
Constructor homing emits the complete type info for a class only when the
constructor is emitted, so it is expected that there will be some classes that
are not defined in the debug info anymore because they are never constructed,
and we shouldn't need debug info for these classes.
I compared the PDB files for clang, and there are 273 class types that are defined with `=limited`
but not with `=constructor` (out of ~60,000 total class types).
We've looked at a number of the types that are no longer defined with =constructor. The vast
majority of cases are something like class A is used as a parameter in a member function of
some other class B, which is emitted. But the function that uses class A is never called, and class A
is never constructed, and therefore isn't emitted in the debug info.

This time without the change to make operator| use operator&=.
That seems to be the source of the gcc 5.3 miscompile.
Original commit message:
These represent the same thing but 64BIT only showed up from
getHostCPUFeatures providing a list of featuers to clang. While
EM64T showed up from getting the features for a named CPU.
EM64T didn't have a string specifically so it would not be passed
up to clang when getting features for a named CPU. While 64bit
needed a name since that's how it is index.
Merge them by filtering 64bit out before sending features to clang
for named CPUs.
This is practically NFC at the moment because nothing really
asks the real number or does anything useful with it.

Summary:
Ignore callback uses when adding a callback function
in the CallGraph. Callback functions are typically
created when outlining, e.g. for OpenMP, so they have
internal scope and linkage. They should not be added
to the ExternalCallingNode since they are only callable
by the specified caller function at creation time.
A CGSCC pass, such as OpenMPOpt, may need to update
the CallGraph by adding a new outlined callback function.
Without ignoring callback uses, adding breaks CGSCC
pass restrictions and results to a broken CallGraph.

This handles all three places where attributes could currently be - `GlobalVariable`, `Function` and `CallBase`.
For last two, it correctly handles all three possible attribute locations (return value, arguments and function itself)
There was a previous attempt at it D73853,
which was committed in rGfc62b36a000681c01e993242b583c5ec4ab48a3c,
but then reverted all the way back in rGb12176d2aafa0ccb2585aa218fc3b454ba84f2a9
due to some (osx?) test failures.

Summary:
As per disscussion in D83351, using `for_each` is potentially confusing,
at least in regards to inconsistent style (there's less than 100 `for_each`
usages in LLVM, but ~100.000 `for` range-based loops
Therefore, it should be avoided.

There are bugs where you don't want the signal handler to trigger, most
notably when that will cause another crash. Examples of this are lldb
running out of memory or a bug in the reproducer generation code. This
adds an escape hatch trough a (developer oriented) flag to not install
the signal handler.
