[SDAG] add demanded bits transform for bswap

A possible codegen regression for PowerPC is noted in D117406
because we don't recognize a pattern that demands only 1 byte
from a bswap.

This fold  has existed in IR since close to the beginning of LLVM:
https://github.com/llvm/llvm-project/blame/main/llvm/lib/Transforms/InstCombine/InstCombineSimplifyDemanded.cpp#L794
...so this patch copies that code as much as possible and adapts
it for SDAG.

The test for PowerPC that would change in D117406 is over-reduced
with undefs, so I recreated it for AArch64 and x86 by passing in
pointer args and renamed the values to make the logic clearer.

[GlobalOpt] Generalize malloc-to-global for any allocation function

We can generalize the malloc-to-global transform for other allocation functions which are both a) removable, and b) have a known initialization value.

One subtlety that I want to point out - mostly because I hadn't realized it was true until I took a closer look - is that the existing code doesn't prove that initialization/malloc happens only once. The initialization function can be called multiple times. This is correct without special handling for malloc as undef can map to any value previously written, but a non-undef initializing allocation it means we may end up memseting the new global repeatedly. In particular, this means it's not legal to fold the memset into the initializer of the global.

makes sense to use SIGN_EXTEND because this may improve code quality in
some cases, particularly when doing a constant splat of an unpacked vector
type. For example, for SVE when splatting the value -1 into all elements
of a vector of type <vscale x 2 x i32> the element type will get promoted
from i32 -> i64. In this case we want the splat value to sign-extend from
(i32 -1) -> (i64 -1), whereas currently it zero-extends from
(i32 -1) -> (i64 0xFFFFFFFF). Sign-extending the constant means we can use
a single mov immediate instruction.

[LLDB] Fix Python GIL-not-held issues

The GIL must be held when calling any Python C API functions. In multithreaded applications that use callbacks this requirement can easily be violated by accident. A general tool to ensure GIL health is not available, but patching Python Py_INCREF to add an assert provides a basic health check:

```
+int PyGILState_Check(void); /* Include/internal/pystate.h */
+
 #define Py_INCREF(op) (                         \
+    assert(PyGILState_Check()),                 \
     _Py_INC_REFTOTAL  _Py_REF_DEBUG_COMMA       \
     ((PyObject *)(op))->ob_refcnt++)

 #define Py_DECREF(op)                                   \
     do {                                                \
+        assert(PyGILState_Check());                     \
         PyObject *_py_decref_tmp = (PyObject *)(op);    \
         if (_Py_DEC_REFTOTAL  _Py_REF_DEBUG_COMMA       \
         --(_py_decref_tmp)->ob_refcnt != 0)             \
```

Adding this assertion causes around 50 test failures in LLDB. Adjusting the scope of things guarded by `py_lock` fixes them.

Alex Zinenko [Fri, 14 Jan 2022 16:25:41 +0000 (17:25 +0100)]
[mlir] fix crash in PybindAdaptors.h

The constructor function was being defined without indicating its "__init__"
name, which made it interpret it as a regular fuction rather than a
constructor. When overload resolution failed, Pybind would attempt to print the
arguments actually passed to the function, including "self", which is not
initialized since the constructor couldn't be called. This would result in
"__repr__" being called with "self" referencing an uninitialized MLIR C API
object, which in turn would cause undefined behavior when attempting to print
in C++.

Fix this by specifying the correct name.

This in turn uncovers the fact the the mechanism used by PybindAdaptors.h to
bind constructors directly as "__init__" functions taking "self" is deprecated
by Pybind. The modern method requires using "py::init", which seems to rely on
the C++ equivalent of the bound class to be available, which is not the case in
PybindAdaptors.h. A deeper inspection shows that the deprecation concerns
old-style pybind11 constructors that had to allocate the object using
placement new with "self" as memory. The PybindAdaptors.h only provides
extension classes and never allocates (the object construction is delegated to
the base class), so it does not use the deprecated functionality. Use the
implementation detail tag class to convince pybind11 that we are using the
modern constructor binding method and suppress the warning.

On top of that, the definition of the function was incorrectly indicated as the
method on the "None" object instead of being the method of its parent class.
This would result in a second problem when Pybind would attempt to print
warnings pointing to the parent class since the "None" does not have a
"__name__" field or its C API equivalent.

Fix this by specifying the correct parent class by looking it up by name in the
parent module.

[GlobalOpt] Use generic type when converting malloc to global

The malloc to global transform currently determines the type of the
global by looking at bitcasts of the malloc. This is limited (the
transform fails if there are multiple different types) and
incompatible with opaque pointers.

My initial approach was to construct an appropriate struct type
based on usage in loads/stores. What this patch does instead is
to always create an [i8 x AllocSize] global, without trying to
guess types at all.

This does mean that other transforms that require a certain global
type may break. I fixed two of these in D117034 and D117223, which
I believe should be sufficient to avoid regressions. In particular,
the global SRA change should end up splitting the global into
naturally-typed sub-globals, at which point all other optimizations
should work.
