61c74dc4d5 Fix production of R_X86_64_GOTPCRELX/R_X86_64_REX_GOTPCRELX. 
We were producing R_X86_64_GOTPCRELX for invalid instructions and
sometimes producing R_X86_64_GOTPCRELX instead of
R_X86_64_REX_GOTPCRELX.

aea5485cfe [x86] avoid printing unnecessary sign bits of hex immediates in asm comments (PR20347) 
It would be better to check the valid/expected size of the immediate operand, but this is
generally better than what we print right now.

5cfb6469b8 [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.

1369b53da1 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).
