Med Ismail Bennani 0d7401cf9d [lldb/api] Add checks for StackFrame::GetRegisterContext calls (NFC) ...

This patch fixes a crash that is happening because of a null pointer
dereference in SBFrame.

StackFrame::GetRegisterContext says explicitly that you might not get
a valid RegisterContext back but the pointer wasn't tested before,
resulting in crashes. This should solve the issue.
