Denis Revunov abc1f33298 [BOLT][AArch64] Replace NOP with adrp in AdrRelaxationPass to preserve relative offsets. ...

Avoid replacing one adr instruction with two adrp+add by utilizing linker-provided nops
when they are present. By doing so we preserve relative offsets of next instructions
in a function which reduces chances to break undetected jump tables. This commit makes
release-mode lld-linked clang, lld and etc work after BOLT.
