Log:
  Merge commit 2e24219d3 from llvm git (by Hans Wennborg):

    [MC][ARM] Resolve some pcrel fixups at assembly time (PR44929)

    MC currently does not emit these relocation types, and lld does not
    handle them. Add FKF_Constant as a work-around of some ARM code after
    D72197. Eventually we probably should implement these relocation
    types.

    By Fangrui Song!

    Differential revision: https://reviews.llvm.org/D72892

  This re-enables using the arm 'adr' pseudo instruction on global symbols
  again.  It was broken as a side-effect of upstream commit 2bfee35cb,
  which lead to "error: unsupported relocation on symbol" when assembling
  such constructs, which are used in e.g. sys/arm/arm/locore-v[46].S.
