[PATCH] D142191: [lld][RISCV] Merge subtarget features to get right attributes section

[Elena Lepilkina via Phabricator via llvm-commits]

> Target features in a function must not leak outside a function.

All target extensions are placed there and there is already such usage in https://github.com/llvm/llvm-project/blob/main/llvm/lib/Target/RISCV/RISCVTargetMachine.cpp#L127. Where should I get extensions information in bitcode file from?

Unfortuantely, I can't find now the comment in code, but I exactly remember the comment that target features for linker in taken from bitcode functions attributes + if `-mattr` is provided is taken from there also.
