GenerateTruncates at the moment creates extends/truncates for post-inc
uses of normalized expressions. For example, if an add rec of the form
{1,+,-1} is used outside the loop, the normalized form will use {1,+,-1}
instead of {0,+,-1}. When naively sign-extending the normalized
expression, it will get extended incorrectly to {1,+,-1} for the wider
type, if the backedge-taken count of the loop is 1.
To address this, the patch updates GenerateTruncates to check if the
LSRUse contains any fixups with PostIncLoops. If that's the case, first
de-normalize the expression, then perform the extend/truncate, then
normalize again.
There may be other places where similar checks are needed and the helper

[RISCV] Fix a latent miscompile in doPeepholeMaskedRVV
The code was using the tail policy being "agnostic" to select a instruction whose semantics were "undefined". This was almost always fine (as the pass through operand was usually implicit_def), but could in theory lead to a miscompile. I don't actually have a test case as it requires a later transform to exploit the wrong tail policy state, and I couldn't easily figure out to get vsetvli insertion to miscompile given the wrong state. This was spotted by inspection, and it may be a miscompile in theory only at the moment.
Note that this may cause regressions if there are instructions for which we either don't have a _TU pseudo form, or the _TU pseudo form is missing a policy operand. When I was first looking at this, I saw exactly that, and D153067 exists to add the missing policy operand I noticed.

[dsymutil] Fix .debug_addr index calculation
The DW_OP_addrx operation encodes a zero-based index into the
.debug_addr section. The index is relative to the DW_AT_addr_base
attribute of the associated compilation unit. In order to compute the
offset into the .debug_addr section and find the associated relocation,
we need to add the add the add base offset and multiply the index with
the address size.
This patch fixes a bug in this computation, where the multiplication was
omitted. This went unnoticed because for small test cases, the index for
interesting addresses (such as the main subprogram) is often zero.

AMDGPU: Remove unnecessary Attributor overrides

AMDGPU: Propagate amdgpu-waves-per-eu with attributor
This will do a value range merging down the callgraph, unlike the
current pass which can only propagate values to undecorated functions
from a kernel.
This one is a bit weird due to the interaction with the implied range
from amdgpu-flat-workgroup-size. At the default group range of 1,1024,
the minimum implied bounds is 4 so this ends up introducing the
attribute on undecorated functions. We could probably simplify this by
ignoring it and propagating the raw values. The subtarget interaction
and the interaction with amdgpu-flat-workgroup-size only really clamp
invalid values (plus the lower bound doesn't seem to do anything as
far as I can tell anyway).

[RISCV] Refactor how we create separate instructions for F and Zfinx. NFC
Previously we had a ExtInfo_rr class that was instantiated for
every combination of types that can appear together along with
their predicates, suffixes, and decoder namespace.
This patch replaces this with a new ExtInfo class that contains
predicates, suffix, namespace, and the f16, f32, and f64 DAGOperands
implied by the predicates. The DAGOperand can be unset if
the predicate is not enough to distinquish it.
At every instruction instantiation we know whether the operands
are GPR, f16, f32, or f64 and can ask the ExtInfo for the relevant
DAGOperand.
The foreach loops of ExtInfo have been moved out of the classes to
be at the top level of the 3 files. This allows the file to pick
the f16/f32/f64 DAGOperand per instruction and pass it down to the
classes separately from the ExtInfo. The ExtInfo still needs to be
passed down to get suffix, predicates, and decoder namespace.

[DebugInfo] Change DWARFDebugAbbrev initialization
I plan on adding better error handling to DWARFDebugAbbrev, but first I
want us to be able to better reason about a state of a DWARFDebugAbbrev.
I want us to be able to initialize a DWARFDebugAbbrev in its complete
state instead of creating it and then calling an `extract` method
manually. If its Data field is populated, then parsing is not complete.
If Data is `std::nullopt`, then parsing is done and this section is
"finalized" in some sense.
Additionally, I have removed the `clear()` method. This makes sense for other
classes like DWARFAbbreviationDeclaration where we may want to re-use an object
repeatedly to avoid repeated initializations and allocations, but for
DWARFDebugAbbrev we pretty much create one and stick with it.
