CI: Bump LDC-LLVM to v20.1.3

There's a 32-bit x86 optimizer (?) regression blocking more CI results for the Win32 and Linux multilib CI jobs. This hits an LLVM 20 assertion:

$ bin/ldc2 -c -unittest ../ldc/runtime/druntime/src/core/internal/container/array.d -d-version=CoreUnittest -m32 -release -O
ldc2: /home/martin/dev/llvm-project/llvm/include/llvm/ADT/APInt.h:127: llvm::APInt::APInt(unsigned int, uint64_t, bool, bool): Assertion `llvm::isUIntN(BitWidth, val) && "Value is not an N-bit unsigned value"' failed.

Edit: Seems to happen for all 32-bit targets, at least for Android ARMv7-A and riscv32.

I can take a look.
Sorry, I was busy with a lot of IRL stuff recently and was unable to do anything else.

[kinke]

No worries! - Yeah it'd be great if you could look into that problem.

The same LLVM assertion is also hit for lit-test dynamiccompile/bind_bool.d, on macOS (where it's the single remaining failure for both x86_64 and arm64 archs) and Linux aarch64.

Looks like the other remaining failures on non-macOS are all dynamic-compile related - 4 hanging lit-tests on Windows x64 (incl. bind_bool.d), and 28 failures on Linux aarch64 (seemingly getting a signal 2 - interrupt).
