[clang-format] Fix incorrect isspace input (NFC)
This change fixes a clang-format unit test failure introduced by [D124748](https://reviews.llvm.org/D124748). The `countLeadingWhitespace` function was calling `isspace` with values that could fall outside the valid input range. The valid input range for `isspace` is unsigned 0-255. Values outside this range produce undefined behavior, which on Windows manifests as an assertion being raised in the debug runtime libraries. `countLeadingWhitespace` was calling `isspace` with a signed char that could produce a negative value if the underlying byte's value was 128 or above, which can happen for non-ASCII encodings. The fix is to use `StringRef`'s `bytes_begin` and `bytes_end` iterators to read the values as unsigned chars instead.
This bug can be reproduced by building the `check-clang-unit` target with a DEBUG configuration under Windows. This change is already covered by existing unit tests.

[trace] Make events first class items in the trace cursor and rework errors
We want to include events with metadata, like context switches, and this
requires the API to handle events with payloads (e.g. information about
such context switches). Besides this, we want to support multiple
similar events between two consecutive instructions, like multiple
context switches. However, the current implementation is not good for this because
we are defining events as bitmask enums associated with specific
instructions. Thus, we need to decouple instructions from events and
make events actual items in the trace, just like instructions and
errors.
- Add accessors in the TraceCursor to know if an item is an event or not
- Modify from the TraceDumper all the way to DecodedThread to support
- Renamed the paused event to disabled.
- Improved the tsc handling logic. I was using an API for getting the tsc from libipt, but that was an overkill that should be used when not processing events manually, but as we are already processing events, we can more easily get the tscs.
event items. Fortunately this simplified many things
- As part of this refactor, I also fixed and long stating issue, which is that some non decoding errors were being inserted in the decoded thread. I changed this so that TraceIntelPT::Decode returns an error if the decoder couldn't be set up proplerly. Then, errors within a trace are actual anomalies found in between instrutions.

lowerConstant() currently accepts a number of constant expressions

The motivation here is to clarify which constant expressions are

[clang][flang] Disable defaulting to `-fpie` for LLVM Flang
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.

[ArgPromotion] Remove all the getters and ReplaceCallSite (NFC)
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

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.
