This is still going to be a bit slow. I think we should use the following scheme to minimize the number of large `.space` as well as testing the real range.

    FileCheck ... --implicit-check-not=error:
  
    .p2align 2
  # CHECK: [[#@LINE+1]]:3: error: fixup value out of range
    adr x0, adr1-8
    adr x0, adr1-8
  adr0:
    .space (1<<20)
  adr1:
    adr x0, adr0
  # CHECK: [[#@LINE+1]]:3: error: fixup value out of range
    adr x0, adr0
