[BitCode] Add noprofile to getAttrFromCode()

After D104475 / D104658, building the Linux kernel with ThinLTO is
broken:

ld.lld: error: Unknown attribute kind (73) (Producer: 'LLVM13.0.0git'
Reader: 'LLVM 13.0.0git')

getAttrFromCode() has never handled this attribute so it is written
during the ThinLTO phase but it cannot be handled during the linking
phase.

Add noprofile to getAttrFromCode() so that disassembly works properly.
