b47aceaf06 Revert "BlockFrequency: Saturate at 1 instead of 0 when multiplying a frequency with a branch probability." 
This reverts commit r184584. Breaks PPC selfhost.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184590 91177308-0d34-0410-b5e6-96231b3b80d8

93702a3b07 BlockFrequency: Saturate at 1 instead of 0 when multiplying a frequency with a branch probability. 
Zero is used by BlockFrequencyInfo as a special "don't know" value. It also
causes a sink for frequencies as you can't ever get off a zero frequency with
more multiplies.

This recovers a 10% regression on MultiSource/Benchmarks/7zip. A zero frequency
was propagated into an inner loop causing excessive spilling.

PR16402.

84569698f0 [PowerPC] Support R_PPC_REL16 family of relocations 
The GNU assembler supports (as extension to the ABI) use of PC-relative
relocations in half16 fields, which allows writing code like:

  li 1, base-.

This patch adds support for those relocation types in the assembler.

cab0a19338 [PowerPC] Support various tls-related modifiers 
The current code base only supports the minimum set of tls-related
relocations and @modifiers that are necessary to support compiler-
generated code.  This patch extends this to the full set defined
in the ABI (and supported by the GNU assembler) for the benefit
of the assembler parser.
