For this sample:
@interface Foo
@property id x;
@end
we get:
t.m:2:1: error: ARC forbids properties of Objective-C objects with unspecified storage attribute
@property id x;
^
1 error generated.
The error should be imposed on the implementor of the interface, not the user. If the user uses
a header of a non-ARC library whose source code he does not have, we are basically asking him to
go change the header of the library (bad in general), possible overriding how the property is
implemented if he gets confused and says "Oh I'll just add 'copy' then" (even worse).
Second issue is that we don't emit any error for 'readonly' properties, e.g:
@interface Foo
@property (readonly) id x; // no error here
@end
@implementation Foo
@synthesize x; // no error here too
@end
We should give an error when the implementor is @synthesizing a property which doesn't have
any storage specifier; this is when the explicit specifier is important, because we are
going to create an ivar and we want its ownership to be explicit.
Related improvements:
-OBJC_PR_unsafe_unretained turned out to not fit in ObjCPropertyDecl's bitfields, fix it.
-For properties of extension classes don't drop PropertyAttributesAsWritten values.
-Have PropertyAttributesAsWritten actually only reflect what the user wrote

Also made:
(lldb) !<NUM>
(lldb) !-<NUM>
(lldb) !!
work with the history. For added benefit:
(lldb) !<NUM><TAB>
will insert the command at position <NUM> in the history into the command line to be edited.
This is only partial, I still need to sync up editline's history list with the one kept by the interpreter.

- a new --name option for "type summary add" lets you give a name to a summary
- a new --summary option for "frame variable" lets you bind a named summary to one or more variables
${var%s} now works for printing the value of 0-terminated CStrings
type format test case now tests for cascading
- this is disabled on GCC because GCC may end up stripping typedef chains, basically breaking cascading
new design for the FormatNavigator class
new template class CleanUp2 meant to support cleanup routines with 1 additional parameter beyond resource handle

LinearFunctionTestReplace rewrite. No functionality.
I've been wanting to group the indvar subphases into sections and
order them by their logical sequence. My next checkin adds functions
related to LFTR, and doing the reorg now should help reviewers. Since,
most of the code in IndVarSimplify.cpp has recently been replaced or
will be replaced soon, obscuring blame should not be an issue. This
seems like an ideal time to shuffle the code around.
I'm happy to take more suggestions for cleaning up the code. Or if
you've been wanting to cleanup anything in this file yourself, now is
a good time.

is just wrong and resulted in the inferior's output getting mixed into the GDB remote communication's
log file. Change all test cases to not pass os.ctermid() and either use SBTarget.LaunchSimple() or
SBTarget.Launch() and pass None as stdin_path/stdout_path/srderr_path to use a pseudo terminal.

we want (and if it does, some improvements are needed before relying on it).
