updpatch: ldc 3:1.35.0-1

LDC is finally working again on riscv64. This is the first of two
patches in order to realign LDC with current Arch environment.

- Link to LLVM 14 to match previously built version long ago. Will
switch to LLVM 16 in the next patch.
- Add some temporary atomic hacks to make compiler happy, since previous
GCC atomic hacks were replaced by actual upstream implementation.
