3315e168ee 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.

3720d45002 [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.

d5bb2945ff [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.

f9939fdb3c [PECOFF] Remove COFF header from PE header for simplicity. 
COFF header is always present both in executable and in object file. PE header
is present only in executable. So the natural way to handle PE/COFF file is
treating COFF is mandatory header and PE is optional. Current data structre
does not allow it, because PE header includes COFF header. Removing COFF
header will simplify the code to handle PE/COFF files.
