[SPARC][IAS] Adjust bounds check in %rX name parsing (#218301)
Fix an off-by-one error that results in %r31 being incorrectly rejected.
This was reported by the folks at OpenBSD.
EC2: Enable autogrowing filesystems post-boot
Enable the new growfs_postboot mechanism. Note that this also implies
disabling automatic allocation of swap space on the root disk, since we
cannot grow the root filesystem if swap space is allocated after it.
This will not be MFCed since it is a significant behavioural change.

rc+devd: Add growfs_postboot
In VM and cloud environments it is often possible to enlarge virtual
disks; this can be useful, for example, if a system is launched with a
small root disk and it later becomes clear that more space is needed.
On kernels which support run-time resizing of disks (for NVMe, this was
added in November 2025; some other disk types have supported this for
longer) a SIZECHANGE notification is sent to userland via devd.
Add a "nostart" rc.d script (runnable manually but not automatically at
boot time) and a devd script which invokes it when a notification
arrives. The rc.d script enlarges the "final partition" on partitioned
geoms, or the UFS filesystem or zpool device when triggered on a disk
containing either of those.

[BOLT] Add option --merge-text-sections (#217732)
With BOLT optimization enabled the output carries the new hot code in
.text and the cold code in .text.cold, allocated back to back in the
same segment. Some consumers may prefer a single .text covering both.
The two text sections are already in one contiguous address range, so
only the section header table separates them. Under this new option
"--merge-text-sections" the lowest addressed code section keeps the
header, reports the extent of the whole run under the name .text, and
the rest are marked anonymous so no header is written for them. Their
contents and addresses are untouched, which keeps the emitted code byte
for byte identical to the one built without the option.
Symbols defined in a folded section, such as cold fragments, take the
index of the merged section so they won't end up referencing SHN_UNDEF.
Each folded section also gets a local marker symbol, named as
".bolt.pre_merge<original_section_name>", recording the name and start
address it had before the merge, so the previous layout stays

[VectorCombine] Support simplification to scalar store for multiple insertelt (#132820)
VectorCombine already folds a load–insertelement–store sequence
containing
a single insertion into a scalar store. Extend this fold to chains of
insertelement instructions:
V0 = load vector from p
V1 = insertelement V0, x1, i1
...
Vn = insertelement V(n-1), xn, in
store Vn to p
=>
store x1 to element i1 of the vector at p
...
store xn to element in of the vector at p

[flang] Do not branch to a FORMAT statement from an assigned GO TO
Label analysis already classifies which labeled statements may be named by
a statement that branches. Record the positions of those statements in the
semantics context and consult it when lowering records the targets of an
assigned GO TO, so that a FORMAT statement is not given a target block.
A GO TO whose variable holds only a format label now reaches the run-time
error instead of branching into the FORMAT statement.
The label analysis is built once and shared: AnalyzeLabels() runs the
constraint checks first and records the branch targets only if they pass,
since a program with fatal errors is not lowered.

[flang] Record the position of a labeled program-unit END statement (#217842)
The END statement of a program unit is visited in advance, before the
statement visitor has moved its current position onto it, so the
position recorded for a label on that statement was whatever statement
came last -- a null source position for the first program unit in a
file, and the preceding unit's position for the others. Pass the
statement position to AddTargetLabelDefinition explicitly instead of
reading it from the visitor.
A diagnostic anchored on such a label had no location to report:
```fortran
subroutine s(j)
integer :: j
write(*,fmt=40)
go to j
40 end subroutine
```
