Zachary Turner 0d43c1c339 [pdb] Finish conversion to zero copy pdb access. 
This converts remaining uses of ByteStream, which was still
left in the symbol stream and type stream, to using the new
StreamInterface zero-copy classes.

RecordIterator is finally deleted, so this is the only way left
now.  Additionally, more error checking is added when iterating
the various streams.

With this, the transition to zero copy pdb access is complete.

Renato Golin 9be88629d5 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... :(

Krzysztof Parzyszek 96bb4fe539 [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.

Matt Arsenault 7401516985 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.

Evgeny Stupachenko ea2aef4a1d 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).
