including the amended (no UB anymore) fix for adding/subtracting -2147483648.

This reverts r298328 "[ARM] Revert r297443 and r297820."
and partially reverts r297842 "Revert "[Thumb1] Fix the bug when adding/subtracting -2147483648""

Eli Friedman 76732acc23 [ARM] Revert r297443 and r297820.
The glueless lowering of addc/adde in Thumb1 has known serious
miscompiles (see https://reviews.llvm.org/D31081), and r297820
causes an infinite loop for certain constructs.  It's not
clear when they will be fixed, so let's just take them out
of the tree for now.

(I resolved a small conflict with r297453.)

same as already done for ARM and Thumb2.

David Blaikie a79ac14fa6 [opaque pointer type] Add textual IR support for explicit type parameter to load instruction
Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

import fileinput
import sys
import re

pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)")

for line in sys.stdin:
  sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

Dale Johannesen 0659c8f157 These tests are looking for library function names that
appear to differ on Linux.  Try to make them pass on Linux.
Would be good for a Linux person to review this.
