Breakpad processor: Save Windows unwinding data earlier in x86 walker.
Breakpad processor: Save Windows unwinding data earlier in x86 walker.

At the moment, StackwalkerX86::GetCallerFrame doesn't save the
WindowsFrameInfo that it finds for a frame unless it successfully
constructs the caller frame. This means that the windows_frame_info
field of the last frame on the stack is left unset, even when that
frame does have windows unwinding information.

This is not user-visible behavior, so it doesn't matter, but it is a
blemish on the interface, and unit tests (added in a later patch)
expect it.

This patch saves the information in the frame as soon as we find it.
