When passing --discover-cycles and --show-counts, it displays
the number of dependencies between each hop of the cycle,
and sorts by the sum. Dependencies at the top of the list
should be the easiest to break.

The alias was only ever used on darwin and had some issues there,
and isn't used in practice much. Also fixes a problem with -mno-altivec
not turning off -maltivec.
Also add a diagnostic for faltivec/fno-altivec that directs users to use
maltivec options and include the altivec.h file explicitly.

Fix two problems related to r298025:
- SplitKit would create duplicate VNIs in some cases leading to crashs
when hoisting copies.
- VirtRegMap could fail expanding copies at the beginning of a basic

Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.
Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

A bool is represented by a single byte, which the ARM ABI requires to be either
0 or 1. So we cannot use G_ANYEXT when legalizing the type.

StringMap's iterators did not support LLVM's
iterator_facade_base, which made it unusable in various
STL algorithms or with some of our range adapters.
This patch makes both StringMapConstIterator as well as
StringMapIterator support iterator_facade_base.
With this in place, it is easy to make an iterator adapter
that iterates over only keys, and whose value_type is
StringRef. So I add StringMapKeyIterator as well, and
provide the method StringMap::keys() that returns a
range that can be iterated.

ADL as reasonable extension points.
All of this would be cleaner if this code followed the more usual LLVM
convention of not having deeply nested namespaces inside of .cpp files
and instead having a `using namespace ...;` at the top. Then the static
function would be in the global namespace and easily referred to as
`::join`. Instead we have to write a fairly contrived qualified name.
I figure the authors can clean this up with a less ambiguous name, using
the newly provided LLVM `join` function, or any other solution, but this
at least fixes the build.

This adds a parameter to @llvm.objectsize that makes it return

Because SamplePGO passes will be invoked twice in ThinLTO build: once at compile phase, the other at backend. We want to make sure the IR at the 2nd phase matches the hot part in pro

For variables in generic address spaces, for example:
```
unsigned char V[6442450944];
...
```
the address space is not yet known when we get into
*getConstantArrayType*, it is 0. AMDGCN target's
address space 0 has 32 bits pointers, so when we
call *getPointerWidth* with 0, the array size is
trimmed to 32 bits, which is not right.

This is a fixup for the unit tests from r298278 (originally r298165).
Since the buffer that RawB2 pointed at was later deleted, a new call to
getBuffer may very well return a buffer at the same/old address. Which is
fine. Just delete the spurious check.
A Windows bot was occasionally hitting this in practice:

Summary: check_cxx_compiler_flag and check_library_exists could fail because they ignored CMAKE_EXE_LINKER_FLAGS and therefore would always fail to produce executables. Cmake policy CMP0056 fixes this, but was explicitly set to OLD in our CMakeLists because it caused problems with test_target_arch. This change sets the policy to NEW to fix the problem with the compiler and library tests, and temporarily clears CMAKE_EXE_LINKER_FLAGS inside test_target_arch to emulate the old behavior there. This allows, for example, LTO builds that require lld to succeed.

Based on the comment in the test, and my reading of the standard, a deprecated warning should be issued in the following case:
template<typename T> [[deprecated]] class Foo{}; Foo<int> f;
This was not the case, because the ClassTemplateSpecializationDecl creation did not also copy the deprecated attribute.
Note: I did NOT audit the complete set of attributes to see WHICH ones should be copied, so instead I simply copy ONLY the deprecated attribute.
