[Support] Add a way to run a function on a detached thread
This roughly mimics `std::thread(...).detach()` except it allows to
customize the stack size. Required for https://reviews.llvm.org/D50993.
I've decided against reusing the existing `llvm_execute_on_thread` because
it's not obvious what to do with the ownership of the passed
function/arguments:
1. If we pass possibly owning functions data to `llvm_execute_on_thread`,
we'll lose the ability to pass small non-owning non-allocating functions
for the joining case (as it's used now). Is it important enough?
2. If we use the non-owning interface in the new use case, we'll force
clients to transfer ownership to the spawned thread manually, but
similar code would still have to exist inside
`llvm_execute_on_thread(_async)` anyway (as we can't just pass the same
non-owning pointer to pthreads and Windows implementations, and would be
forced to wrap it in some structure, and deal with its ownership.

[DebugInfo] Stop describing imms in TargetInstrInfo's describeLoadedValue() impl
Summary:
The default implementation of the describeLoadedValue() hook uses the
MoveImm property to determine if an instruction moves an immediate. If
an instruction has that property the function returns the second
operand, assuming that that is the immediate value the instruction
moves. As far as I can tell, the MoveImm property does not imply that
the second operand is the immediate value, nor that any other operand
necessarily holds the immediate value; it just means that the
instruction moves some immediate value.
One example where the second operand is not the immediate is SystemZ's
LZER instruction, which moves a zero immediate implicitly: $f0S = LZER.
That case triggered an out-of-bound assertion when getting the operand.
I have added a test case for that instruction.
Another example is ARM's MVN instruction, which holds the logical
bitwise NOT'd value of the immediate that is moved. For the following
reproducer:
extern void foo(int);
int main() { foo(-11); }
an incorrect call site value would be emitted:
$ clang --target=arm foo.c -O1 -g -Xclang -femit-debug-entry-values \
-c -o - | ./build/bin/llvm-dwarfdump - | \
grep -A2 call_site_parameter
0x00000058: DW_TAG_GNU_call_site_parameter
DW_AT_location (DW_OP_reg0 R0)
DW_AT_GNU_call_site_value (DW_OP_lit10)
Another example is the A2_combineii instruction on Hexagon which moves
two immediates to a super-register: $d0 = A2_combineii 20, 10.
Perhaps these are rare exceptions, and most MoveImm instructions hold
the immediate in the second operand, but in my opinion the default
implementation of the hook should only describe values that it can, by
some contract, guarantee are safe to describe, rather than leaving it up
to the targets to override the exceptions, as that can silently result
in incorrect call site values.
This patch adds X86's relevant move immediate instructions to the
target's hook implementation, so this commit should be a NFC for that
target. We need to do the same for ARM and AArch64.

There's no behavior change - just moving DependencyScanningTool to its own file
since this tool can be reused across both clang-scan-deps binary and an interface
exposed as part of libClang APIs.

remove multi-argument form of PythonObject::Reset()
Summary:
With this patch, only the no-argument form of `Reset()` remains in
PythonDataObjects. It also deletes PythonExceptionState in favor of
PythonException, because the only call-site of PythonExceptionState was
also using Reset, so I cleaned up both while I was there.
