[Evan Cheng]

Changes in directory llvm/lib/Target:

TargetMachine.cpp updated: 1.41 -> 1.42
---
Log message:

- Added option -relocation-model to set relocation model. Valid values include static, pic,
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.
- Removed options -enable-pic and -ppc-static.
