"compile_units" returns an array of all compile units in a module as a list() of lldb.SBCompileUnit objects.

"compile_unit" returns a compile unit accessor object that allows indexed access, search by full or partial path, or by regex:

(lldb) script
comp_unit = lldb.target.module['TextEdit'].compile_unit['Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit['/path/to/Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit[0]
comp_unit = lldb.target.module['TextEdit'].compile_unit[1]
for comp_unit in lldb.target.module['TextEdit'].compile_unit[re.compile("\.m$")]
  print comp_unit

This helps do quick searches and scripting while debugging.

Warn about null pointer dereference earlier when a reference to a null pointer is
passed in a call. The idea is that even though the standard might allow this, reporting
the issue earlier is better for diagnostics (the error is reported closer to the place where
the pointer was set to NULL). This also simplifies analyzer’s diagnostic logic, which has
to track “where the null came from”. As a consequence, some of our null pointer
warning suppression mechanisms started triggering more often.

Stop the "module" property from throwing an exception when the module name was not found in the target module list.

Added a new module that can dump all line tables for all compile units in any modules that are specified as arguments to the "dump_module_line_tables" command. 

I used this to verify that the debug map line tables were the same as previous LLDB releases prior to my change in the DWARF in .o file linking.

It is possible that some of the current uses of
"getStorageClassAsWritten() == SC_Extern" should use this but I don't know
enough about SC_PrivateExtern to change and test them.

We now emit a line table for each compile unit. To reduce the prologue size
of each line table, the files and directories used by each compile unit are
stored in std::map<unsigned, std::vector< > > instead of std::vector< >.

The prologue for a lto'ed image can be as big as 93K. Duplicating 93K for each
compile unit causes a huge increase of debug info. With this patch, each
prologue will only emit the files required by the compile unit.

Officially in the C++ standard, a null reference cannot exist. However,
it's still very easy to create one:

int &getNullRef() {
  int *p = 0;
  return *p;
}

We already check that binds to reference regions don't create null references.
This patch checks that we don't create null references by returning, either.

No functionality change.

Fixes rdar:13349374.

Volatile loads and stores need to be preserved even if the language
standard says they are undefined. "volatile" in this context means "get
out of the way compiler, let my platform handle it".

Additionally, this is the only way I know of with llvm to write to the
first page (when hardware allows) without dropping to assembly.

- Phi nodes should be replaced/updated after lowering CMOV into branch
  because 'mainMBB' updating operand in Phi node is changed.
- Add EFLAGS in livein before lowering the 2nd CMOV. It's necessary as
  we will reuse the EFLAGS generated before the 1st lowered CMOV, which
  won't clobber EFLAGS. However, we need explicitly specify that.
- '-attr=-cmov' test case are added.

No functionality change at this time.  I've split _LIBCPP_VISIBLE up into two flags: _LIBCPP_TYPE_VIS and _LIBCPP_FUNC_VIS.  This is in preparation for taking advantage of clang's new __type_visibility__ attribute.

The test was marked as expectedFailureLinux, but now it passes with gcc and some versions of clang.  Newer versions of clang introduce a failure due to bad DWARF information.

[analyzer] IDC: Add config option; perform the idc check on first “null node” rather than last “non-null”.

The second modification does not lead to any visible result, but, theoretically, is what we should
have been looking at to begin with since we are checking if the node was assumed to be null in
an inlined function.
