New Revision: 151796

URL: http://llvm.org/viewvc/llvm-project?rev=151796&view=rev
Log:
Remove the sanity checks from RegisterContextLLDB::InitializeZerothFrame
which require a valid CFA address to create a stack frame.  On connecting
to just-starting-up hardware we may have a stack pointer/frame pointer of 0
but we should still create a stack frame so other code in lldb can retrieve
register values via a stackframe.
