Changes in directory llvm/include/llvm/Target:
TargetAsmInfo.h updated: 1.20 -> 1.21
TargetOptions.h updated: 1.11 -> 1.12
---
Log message:
* Fix one more bug in PIC codegen: extra load is needed for *all*
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.
