[lld][ELF] Support LoongArch
This adds support for the LoongArch ELF psABI v2.00 [1] relocation
model to LLD. The deprecated stack-machine-based psABI v1 relocs are not
supported.
The code is tested by successfully bootstrapping a Gentoo/LoongArch
stage3, complete with common GNU userland tools and both the LLVM and
GNU toolchains (GNU toolchain is present only for building glibc,
LLVM+Clang+LLD are used for the rest). Large programs like QEMU are
tested to work as well.

[clang][ConstantEmitter] have tryEmitPrivate[ForVarInit] try ConstExprEmitter fast-path first
As suggested by @efriedma in:
https://reviews.llvm.org/D76096#4370369
This should speed up evaluating whether an expression is constant or
not, but due to the complexity of these two different implementations,
we may start getting different answers for edge cases for which we do
not yet have test cases in-tree (or perhaps even performance regressions
for some cases). As such, contributors have carte blanche to revert if
necessary.
For additional historical context about ExprConstant vs CGExprConstant,
here's snippets from a private conversation on discord:
ndesaulniers:
why do we have clang/lib/AST/ExprConstant.cpp and
clang/lib/CodeGen/CGExprConstant.cpp? Does clang constant fold during
ast walking/creation AND during LLVM codegen?
efriedma:
originally, clang needed to handle two things: integer constant
expressions (the "5" in "int x[5];"), and constant global initializers
(the "5" in "int x = 5;"). pre-C++11, the two could be handled mostly
separately; so we had the code for integer constants in AST/, and the
code for globals in CodeGen/. C++11 constexpr sort of destroyed that
separation, though. so now we do both kinds of constant evaluation on
the AST, then CGExprConstant translates the result of that evaluation
to LLVM IR. but we kept around some bits of the old cgexprconstant to
avoid performance/memory usage regressions on large arrays.

[RISCV] Add lowering for scalar fmaximum/fminimum.
Unlike fmaxnum and fminnum, these operations propagate nan and
consider -0.0 to be less than +0.0.
Without Zfa, we don't have a single instruction for this. The
lowering I've used forces the other input to nan if one input
is a nan. If both inputs are nan, they get swapped. Then use
the fmax or fmin instruction.
New ISD nodes are needed because fmaxnum/fminnum to not define
the order of -0.0 and +0.0.
This lowering ensures the snans are quieted though that is probably not
required in default environment). Also ensures non-canonical nans
are canonicalized, though I'm also not sure that's needed.
Another option could be to use fmax/fmin and then overwrite the
result based on the inputs being nan, but I'm not sure we can do
that with any less code.
Future work will handle nonans FMF, and handling the case where
we can prove the input isn't nan.
This does fix the crash in #64022, but we need to do more work
to avoid scalarization.
