[ObjectYAML][NFC] Hoist BBAddrMap yaml2obj encoder into a shared helper (#205991)
Preparatory NFC refactor to let the upcoming COFF emitter reuse the
BBAddrMap YAML encoder.
devel/py-expression: Add port: Practical functional programming for Python 3.10+
Expression aims to be a solid, type-safe, pragmatic, and high
performance library for frictionless and practical functional
programming in Python 3.10+.

[DA] Rewrite BanerjeeMIV test with safe APInt interval arithmetic
The old banerjeeMIVtest computed inequality bounds using SCEV
arithmetic on 64-bit integers. Intermediate operations like
$(A^{-} - B^{+}) \times Iterations$ could overflow i64 even when all individual
coefficients and loop bounds fit, producing unsound results.
Replace the symbolic bound machinery with a self-contained APInt
interval arithmetic implementation. Key design decisions:
- BanerjeeInterval holds [Lower, Upper] signed-inclusive bounds.
Operations use APInt arithmetic at WideBits, chosen to guarantee no
intermediate overflow:
$$
WideBits = max(8, 2 \times BaseBits + MaxLevels + 8)
$$
This is provably sufficient, each term product needs at most `2 \times BaseBits + 1`
bits, and summing across MaxLevels terms needs at most ceil($\log_2 (MaxLevels)$)
extra bits.

Remove fips-module related diff
This particular change didn't come from upstream. It was added locally
in 7a991ecd1 when attempting to enable the fips provider with 3.0.
Given the fact that we no longer build the fips provider and the fips
provider build process (including sources) is very prescribed to
specific build steps and source versions, there's no reason why we need
to continue carrying around this diff anymore.

exterr_set: sync the definition with the header declaration
This unbreaks buildkernel with TARGET=armv7 (32-bit arm). More work may be required
in order to unbreak `exterr_set` with 32-bit kernels.

[LoongArch] Fix invalid VEXTH combines for unsupported type extensions (#209725)
`performEXTENDCombine` could form `VEXTH`/`VEXTH_U` nodes for
unsupported type combinations, such as extending `v8i8` to `v8i32` or
`v2i64` to `v2i128`. These illegal nodes would later reach instruction
selection and trigger backend failures:
* `Cannot select: LoongArchISD::VEXTH`
* `Don't know how to legalize this operation`
Prevent these combines from firing by verifying that the destination
type is legal and has exactly twice the total bit width of the source
before forming a `VEXTH`/`VEXTH_U` node.
Apply the same checks to `performSHLCombine` for consistency.

[GVN][NFC] Use LoadInst::getProperties() when creating PRE load (#208605)
Use load's properties via getProperties() instead of individually
forwarding isVolatile(), getAlign(), getOrdering() and getSyncScopeID().

[NFC] Reuse DwarfExpression fragment (#210181)
Reuse DwarfExpression fragment information since nothing changes it
between the outside of the loop and the inside of the loop.
