Add TestSymbolAPI.py to test the newly added SBSymbol and SBAddress APIs:
...
lldb::SymbolType SBSymbol::GetType();
lldb::SectionType SBAddress::GetSectionType ();
lldb::SBModule SBAddress::GetModule ();
Also add an lldb::SBModule::GetUUIDString() API which is easier for Python
to work with in the test script.

Added the ability to get a broadcaster event name for a given broadcaster
...
event.
Modified the ProcessInfo structure to contain all process arguments. Using the
new function calls on MacOSX allows us to see the full process name, not just
the first 16 characters.
Added a new platform command: "platform process info <pid> [<pid> <pid> ...]"
that can be used to get detailed information for a process including all
arguments, user and group info and more.

IRgen: Improve GCC compatibility when dealing with packed arrays by propagating

the array alignment to the array access.
- This is more or less the best we can do without having alignment present in
the type system, but is a long way from truly matching how GCC handles this.

Apply again changes to support ARM memory asm parsing. I removed
...
all LDR/STR changes and left them to a future patch. Passing all
checks now.
- Implement asm parsing support for LDRT, LDRBT, STRT, STRBT and
fix the encoding wherever is possible.
- Add a new encoding bit to describe the index mode used and teach
printAddrMode2Operand to check by the addressing mode which index
mode to print.

-Wuninitialized should not warn about variables captured by blocks as byref.

Note this can potentially be enhanced to detect if the __block variable
is actually written by the block, or only when the block "escapes" or
is actually used, but that requires more analysis than it is probably worth
for this simple check.

Adding Static Analyzer checker for mempcpy().
...
Models mempcpy() so that if length is NULL the destination pointer is returned. Otherwise, the source and destination are confirmed not to be NULL and not overlapping. Finally the copy is validated to not cause a buffer overrun and the return value is bound to the address of the byte after the last byte copied.

Mark all uses as <undef> when joining a copy.
...
This way, shrinkToUses() will ignore the instruction that is about to be
deleted, and we avoid leaving invalid live ranges that SplitKit doesn't like.
Fix a misunderstanding in MachineVerifier about <def,undef> operands. The
<undef> flag is valid on def operands where it has the same meaning as <undef>
on a use operand. It only applies to sub-register defines which also read the
full register.
