Mk: generate SBOM .pc files for all ports
Each package and subpackage now installs an SBOM file in pkg-config
format, see pc(5). The file is installed in ${PREFIX}/share/sbom/pc/.
The framework adds it to the plist automatically.

[SelectionDAG] Preserve exact when SimplifyDemandedBits narrows SRL (#235548)
Preserve the `exact` flag when narrowing SRL so a shift combine can drop
a redundant `AND`.
Fixes #231378
[AMDGPU] Price under-aligned memory operations (#233262)
Without unaligned access for the address space, an access aligned below
4 bytes is split into pieces of its alignment. LDS accesses aligned to 4
use 8-byte pieces, and take a 12-byte piece only when aligned to 16 or
when unaligned DS access is enabled.

[AMDGPU] Price memory operations by the number of memory instructions (#233261)
Price a load or store as the number of memory instructions it is split
into.
Constant and buffer "fat" pointers are left alone (for now).

[LoopIdiom] Add a range attribute to formed memset/memcpy/memmove (#226801)
[LoopIdiom] Add a range attribute to formed memset/memcpy/memmove
Attach a range attribute to the length (or, for memset.pattern, the count)
operand. The upper bound comes from the loop's constant maximum backedge-taken
count, and is only recorded if the length is at most 2^16. For a loop like
this...
for (unsigned short i = 0; i < n; ++i)
dst[i] = 0;
...the memset gets `i64 range(i64 0, 65536)`.
LoopIdiomRecognize applies this to memset, memset.pattern, memcpy and memmove
calls.

[NFC][clang][Driver] Collapsed If statements with same return into a single statement in CreateFileHandler (#238231)
This is an NFC PR. It collapses `if` statements with the same `return`
into a single statement. It makes future additions to the code easier
and makes the code more readable.
