PDB/pointers.test was orignally written for 32bit x86 keeping in mind
__cdecl and __stdcall calling conventions which does name mangling for

This is only x86 specific but purpose of pointers.test is NOT to test

Uses of these markers are contrary to all other llvm-project subprojects
and carry no information for people who know the basics of a lit test.
I understand that there is an argument "this makes beginners get started
quickly" but I am unsure whether this is strong enough to deviate from
all other projects. https://llvm.org/docs/TestingGuide.html covers the
basics. Actually, some contributors were confused by the markers.

lowerConstant() currently accepts a number of constant expressions
which have corresponding MC expressions, but which cannot be
evaluated as a relocatable expression (unless the operands are
constant, in which case we'll just fold the expression to a constant).
The motivation here is to clarify which constant expressions are
really needed for https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179,
and in particular clarify that we do not need to support any
division expressions, which are particularly problematic.

Control the MCOperandInfo expansion with `-instr-info-expand-mi-operand-info`.
For X86, this would make it possible to see memory operand type e.g.:
```
/* MOV8rm */
GR8, i8mem,
/* MOV8rm_NOREX */
GR8_NOREX, i8mem_NOREX,
```
The intended use is a follow-up diff D126116 (`getMemOperandSize`).

In, https://reviews.llvm.org/D120305, CLANG_DEFAULT_PIE_ON_LINUX was set
to `On` by default. However, neither `-fpie` nor `-fpic` are currently
supported in LLVM Flang. Hence, in this patch the behaviour controlled
with CLANG_DEFAULT_PIE_ON_LINUX is refined not to apply to Flang.
Another way to look at this is that CLANG_DEFAULT_PIE_ON_LINUX is
currently affecting both Clang and Flang. IIUC, the intention for this
CMake variable has always been to only affect Clang. This patch makes
sure that that's the case.
Without this change, you might see errors like this on X86_64:
```
/usr/bin/ld: main.o: relocation R_X86_64_32 against `.bss' can not be used when making a PIE object; recompile with -fPIC
```
I've not experienced any issues on AArch64. That's probably because on
AArch64 some object files happen to be position independent without
needing -fpie or -fpic.

AARGetter is an abstraction over a source of the `AAResults` introduced
to support the legacy pass manager as well as the modern one. Since the
Argument Promotion pass doesn't support the legacy pass manager anymore,
the abstraction is not required and `AAResults` may be used directly.
The instance of the `FunctionAnalysisManager` is passed through the
functions to get all the required analyses just wherever they are
required and do not use the awkward getter callbacks.
The `ReplaceCallSite` parameter was required for the legacy pass manager
only and isn't used anymore, so the parameter has been eliminated.

The first test shows that combineRangeChecks may choose to keep only two poison conditions.
And we cannot do simple arithmetic or logical and in guard.
The second test shows that keeping two poison conditions in the widened guard may allow
execution of side-effect instruction even if just freeze these conditions.
The third test shows that even in simple test we can hoist a poison and even logical and does not help here.

This changes the implementation of the formatter. Instead of inheriting
from a specialized parser all formatters will use the same generic
parser. This reduces the binary size.
The new parser contains some additional fields only used in the chrono
formatting. Since this doesn't change the size of the parser the fields
are in the generic parser. The parser is designed to fit in 128-bit,
making it cheap to pass by value.
The new format function is a const member function. This isn't required
by the Standard yet, but it will be after LWG-3636 is accepted.
Additionally P2286 adds a formattable concept which requires the member
function to be const qualified in C++23. This paper is likely to be
accepted in the 2022 July plenary.
This is based on D125606. That commit did the groundwork and did similar
changes for the string formatters.
Depends on D128139.

When we fill the shape to tile configure memory, the shape is gotten
from AMX pseudo instruction. However the register for the shape may be
split or spilled by greedy RA. That cause we fill the shape to config
memory after ldtilecfg is executed, so that the shape configuration
would be wrong.
This patch is to split the tile register allocation from greedy register
allocation, so that after tile registers are allocated the shape
registers are still virtual register. The shape register only may be
redefined or multi-defined by phi elimination pass, two address pass.
That doesn't affect tile register configuration.

The current way ot traversing the cursor is a bit uncommon and it can't handle empty traces, in fact, its invariant is that it shold always point to a valid item. This diff simplifies the cursor API and allows it to point to invalid items, thus being able to handle empty traces or to know it ran out of data.
- Removed all the granularity functionalities, because we are not actually making use of that. We can bring them back when they are actually needed.
- change the looping logic to the following:
```
for (; cursor->HasValue(); cursor->Next()) {
if (cursor->IsError()) {
.. do something for error
continue;
}
.. do something for instruction
}
```
- added a HasValue method that can be used to identify if the cursor ran out of data, the trace is empty, or the user tried to move to an invalid position via SetId() or Seek()
- made several simplifications to severals parts of the code.
