46dd534f95 Revert "Revert "Map DynamicNoPIC to Static on non-darwin."" 
This reverts commit r271096, as reverting it broke even more buildbots!

But that also means I'll break on ARM again... :(

421d04a22a [Hexagon] Separate C8 and USR to avoid unwanted subregister composition 
Composing subreg_loreg with subreg_oveflow leads to strange results with
lane masks for register classes with subreg_loreg. In particular, dead
lane detection generates incorrect code.

f5367daffc AMDGPU: Add fract intrinsic 
Remove broken patterns matching it. This was matching the
unsafe math pattern and expanding the fix for the buggy instruction
from the pattern. The problems are also on CI. Remove the workarounds
and only use fract with unsafe math or from the intrinsic.

8323ef30a7 The patch refactors unroll pass. 
Summary:
Unroll factor (Count) calculations moved to a new function.
Early exits on pragma and "-unroll-count" defined factor added.
New type of unrolling "Force" introduced (previously used implicitly).
New unroll preference "AllowRemainder" introduced and set "true" by default.
(should be set to false for architectures that suffers from it).
