1eb812e06d [VE] Fix initializer visibility
Before the change attempt to link libLTO.so against shared
LLVM library failed as:

```
[ 76%] Linking CXX shared library ../../lib/libLTO.so
... /usr/bin/cmake -E cmake_link_script CMakeFiles/LTO.dir/link.txt --verbose=1
c++ -o ...libLTO.so.12git ...ibLLVM-12git.so
ld: CMakeFiles/LTO.dir/lto.cpp.o: in function `llvm::InitializeAllTargetInfos()':
include/llvm/Config/Targets.def:31: undefined reference to `LLVMInitializeVETargetInfo'
```

It happens because on linux llvm build system sets default
symbol visibility to "hidden". The fix is to set visibility
back to "default" for exported APIs with LLVM_EXTERNAL_VISIBILITY.

7e49dc6184 [MC] Change MCCFIInstruction::createDefCfa to cfiDefCfa which does not negate Offset
The negative Offset has caused a bunch of problems and confused quite a
few call sites. Delete the unneeded negation and fix all call sites.
