[mlir][x86] Decouple Accumulator from ADD-Based Vector Contractions (over loops) (#204327)
This path transforms `vector.contract(A, B, Acc)` into
`vector.contract(A, B, 0) + Acc` to decouple the contraction computation
from the accumulator update for contractions over the loop.
[ELF,SPARC] Handle GOTDATA relocations (#213497)
A PIC data reference forms the symbol's GOT offset with
R_SPARC_GOTDATA_OP_HIX22 and R_SPARC_GOTDATA_OP_LOX10 and loads through
it, with R_SPARC_GOTDATA_OP marking the load:
```
sethi %gdop_hix22(sym), %g1
xor %g1, %gdop_lox10(sym), %g1
ldx [%l7 + %g1], %g1, %gdop(sym)
```
When the symbol is neither preemptible nor absolute, optimize the load
to `add %l7, %g1, %g1` over the symbol's GOT-relative address. An
absolute symbol keeps the GOT load, as it can be arbitrarily far from
.got and we don't want the X86_64::relaxOpt complexity.

[JITLink] Remove LTmp workaround now that LLVM requires C++17 (#213428)
C++17 guarantees the postfix-expression naming the called function is
sequenced before evaluation of its arguments, so
L->linkPhase1(std::move(L)) is well-formed without the LTmp indirection.
This should also be implemented by MSVC now. See here (P0145R3 and
P0400R0):
https://learn.microsoft.com/ar-sa/cpp/overview/visual-cpp-language-conformance?view=msvc-170
Disclaimer: As I have no LLVM Windows machine with MSVC at hand, I was
not able to test it myself.
