[Demangle] Implement type D demangling and add all D basic type encodings (#202834)

D basic type encodings to it.
[X86] Fix musttail miscompilation when arguments are passed on the stack (#199691)
After commit 782bf6a, a musttail call with matching CC was always
treated as a sibcall, which skips the stores of outgoing stack
arguments. Any non-forwarded stack argument was silently dropped.
Only treat musttail as a sibcall when every argument is in a register;
otherwise fall back to full tail-call lowering.
Fix #199224

[lldb] Remove ValueObjectRecognizerSynthesizedValue::IsSynthetic override (#199117)
Removes the `IsSynthetic` override on
`ValueObjectRecognizerSynthesizedValue`. This class does not also
override `GetNonSyntheticValue`.
There was a bug in which code assumed that when `IsSynthetic()` returned
true, that `GetNonSyntheticValue` would produce a different value
object. However the default behavior of `GetNonSyntheticValue` is to
return itself.
It seems to me that either:
1. `ValueObjectSynthetic` should be the only class to override
`IsSynthetic` to true
2. or, that classes which override `IsSynthetic` should also override
`GetNonSyntheticValue`
In either case, I think it's best to remove this `IsSynthetic` on
`ValueObjectRecognizerSynthesizedValue`.
NAS-140868 / 26.0.0-RC.1 / Expand reporting tests (#18870) (#19104)
This fixes a schema field name typo for reporting disks (appears in API
docs, but does not change surfaced reporting.realtime event field names
-- typo only was in docs) in addition to adding explicit testing for
internal utilities as well as validating shape of returned responses.
NOTE: this fixes a previously broken merge of branch with same name.
[SelectionDAG] Fold extracts spanning concat operands (#200936)
Factor the extract_subvector-of-CONCAT_VECTORS logic and handle
extracts that cover multiple whole concat operands by rebuilding a
smaller concat directly.
AI note: an LLM generated the code and the test, I've read them
