This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

|

// platforms late 2016 and newer, where lldb will call dyld SPI functions to get

// the _dyld_debugger_notification function we put a breakpoint on give us an
|
|
// array of load addresses for solibs loaded and unloaded. The SPI will tell us
|
|
// about both dyld and the executable, in addition to all of the usual solibs.
