Summary:
This adds -keep-const-init option to llvm-extract which preserves initializers of
used global constants.
For example:
```
$ cat a.ll
@g = constant i32 0
define i32 @f() {
%v = load i32, i32* @g
ret i32 %v
}
$ llvm-extract --func=f a.ll -S -o -
@g = external constant i32
define i32 @f() { .. }
$ llvm-extract --func=f a.ll -keep-const-init -S -o -
@g = constant i32 0
define i32 @f() { .. }
```
This option is useful in checking whether a function that uses a constant global is optimized correctly.
