  [RISCV] Prevent infinite loop after D129980.

D129980 converts (seteq (i64 (and X, 0xffffffff)), C1) into
(seteq (i64 (sext_inreg X, i32)), C1). If bit 31 of X is 0, it
will be turned back into an 'and' by SimplifyDemandedBits which
can cause an infinite loop.

To prevent this, check if bit 31 is 0 with computeKnownBits before
doing the transformation.

Fixes PR56905.

This reverts commit 5fb41342105700949c81f68aefc85d9c46e9a1a6.

This patch is causing crashes when building llvm-test-suite when
optimizing for CPUs with AVX512.

Reproducer crashing with llc:

  [C++2b] [Modules] Handle HaveModules with C++2b

Closing https://github.com/llvm/llvm-project/issues/56803. The root
cause for this bug is that we lack a good method to detect the language
mdoe when parsing the command line. There is a FIXME too. Dut to we lack
a good solution now, keep the workaround.

  [mlir] Fix Analysis/Presburger/Utils.cpp compilation with GCC 11

As reported in Issue #56850, mlir/lib/Analysis/Presburger/Utils.cpp doesn't
compile on Solaris 11.4/SPARC with the bundled GCC 11, as seen when testing
LLVM 15.0.0 rc1:

  /var/llvm/reltest/llvm-15.0.0-rc1/rc1/llvm-project/mlir/include/mlir/Analysis/Presburger/MPInt.h:260:47:
error: inlining failed in call to ‘always_inline’ ‘int64_t
mlir::presburger::int64FromMPInt(const mlir::presburger::MPInt&)’: indirect
function call with a yet undetermined callee

This patch hacks around this and allowed the build to finish.

Tested on `sparcv9-sun-solaris2.11`.
