[dfsan] Support passing non-i16 shadow values in TLS mode
This is a child diff of D92261.
It extended TLS arg/ret to work with aggregate types.
For a function
t foo(t1 a1, t2 a2, ... tn an)
Its arguments shadow are saved in TLS args like
a1_s, a2_s, ..., an_s
TLS ret simply includes r_s. By calculating the type size of each shadow
value, we can get their offset.
This is similar to what MSan does. See __msan_retval_tls and __msan_param_tls
from llvm/lib/Transforms/Instrumentation/MemorySanitizer.cpp.
Note that this change does not add test cases for overflowed TLS
arg/ret because this is hard to test w/o supporting aggregate shdow
types. We will be adding them after supporting that.

Secondly, when we need a maximum, but the user does not supply one,

- A minimum of 1 inlined elements, with more as long as

- If sizeof(T) is "too big", then trigger a static_assert: this dodges
the more pathological cases
This is expected to systematically improve SmallVector use in the

This changes --print-before/after to be a list of strings rather than

great for making it less verbose).
Currently PrintIRInstrumentation passes the class name rather than pass
name to llvm::shouldPrintBeforePass(), meaning
llvm::shouldPrintBeforePass() never functions as intended in the NPM.
There is no easy way of converting class names to pass names outside of
within an instance of PassBuilder.
This adds a map of pass class names to their short names in
PassRegistry.def within PassInstrumentationCallbacks. It is populated
inside the constructor of PassBuilder, which takes a
PassInstrumentationCallbacks.
Add a pointer to PassInstrumentationCallbacks inside
PrintIRInstrumentation and use the newly created map.
This is a bit hacky, but I can't think of a better way since the short
id to class name only exists within PassRegistry.def. This also doesn't
handle passes not in PassRegistry.def but rather added via
PassBuilder::registerPipelineParsingCallback().

[LoopVec] Support non-instructions as argument to uniform mem ops
The initial step of the uniform-after-vectorization (lane-0 demanded only) analysis was very awkwardly written. It would revisit use list of each pointer operand of a widened load/store. As a result, it was in the worst case O(N^2) where N was the number of instructions in a loop, and had restricted operand Value types to reduce the size of use lists.
This patch replaces the original algorithm with one which is at most O(2N) in the number of instructions in the loop. (The key observation is that each use of a potentially interesting pointer is visited at most twice, once on first scan, once in the use list of *it's* operand. Only instructions within the loop have their uses scanned.)
In the process, we remove a restriction which required the operand of the uniform mem op to itself be an instruction. This allows detection of uniform mem ops involving global addresses.

Bump MSVC required version to 19.14
LLVM passes overaligned objects by value, which MSVC 19.1 didn't support on
x86_32. MSVC added this support somewhere between 19.1 and 19.14, but godbolt
doesn't have 19.11, 19.12, or 19.13 so I can't test before 19.14:
https://gcc.godbolt.org/z/75YoEz
Even if users are using the Visual Studio 2017 series of Visual C++ toolchains,
they should've already updated to 19.14 or newer at this point, or they
wouldn't be able to build LLVM. This just raises the CMake required minimum
version so the build fails earlier.

[MemCpyOpt] Correctly merge alias scopes during call slot optimization
When MemCpyOpt performs call slot optimization it will concatenate the `alias.scope` metadata between the function call and the memcpy. However, scoped AA relies on the domains in metadata to be maintained in a caller-callee relationship. Naive concatenation breaks this assumption leading to bad AA results.
The fix is to take the intersection of domains then union the scopes within those domains.
The original bug came from a case of rust bad codegen which uses this bad aliasing to perform additional memcpy optimizations. As show in the added test case `%src` got forwarded past its lifetime leading to a dereference of garbage data.

__sync_fetch_and_sub (32, 64)
__sync_fetch_and_and (32, 64)
__sync_fetch_and_or (32, 64)
__sync_fetch_and_xor (32, 64)
__sync_lock_test_and_set (32, 64)
__sync_val_compare_and_swap (32, 64)
For __sync_fetch_and_sub, internally, it is implemented as
a negation followed by __sync_fetch_and_add.
For __sync_lock_test_and_set, despite its name, it actually
does an atomic exchange and return the old content.
https://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Atomic-Builtins.html
For intrinsics like __sync_{add,sub}_and_fetch and
__sync_bool_compare_and_swap, the compiler is able to generate
codes using __sync_fetch_and_{add,sub} and __sync_val_compare_and_swap.
Similar to xadd, atomic xadd, xor and xxor (atomic_<op>)
instructions are added for atomic operations which do not
have return values. LLVM will check the return value for
__sync_fetch_and_{add,and,or,xor}.
If the return value is used, instructions atomic_fetch_<op>
will be used. Otherwise, atomic_<op> instructions will be used.
All new instructions only support 64bit and 32bit with alu32 mode.
old xadd instruction still supports 32bit without alu32 mode.
For encoding, please take a look at test atomics_2.ll.
