Justin Lebar 468bf73209 Don't claim the udiv created in BypassSlowDivision is exact.
Summary:
In BypassSlowDivision's short-dividend path, we would create e.g.

  udiv exact i32 %a, %b

"exact" here means that we are asserting that %a is a multiple of %b.
But we have no reason to believe this must be true -- this is just a
bug, as far as I can tell.

unittests Switch all DWARF variables for tags, attributes and forms over to use the llvm::dwarf enumerations instead of using raw uint16_t values. This allows easier debugging as users can see the values of the enumerations in the variables view that will show the enumeration string instead of just a number. 2016-10-27 16:32:04 +00:00
