Johnny Chen ea7215f5f8 Added a test case LoadUnloadTestCase.test_dyld_library_path to test launching a process
linked with a dylib which has been relocated by specifying the DYLD_LIBRARY_PATH environment
variable.  Test that the function name breakpoint defined in the dylib is resolved.

Bill Wendling ce4f87b3ba Multiclassify the LDR/STR encoding patterns. The only functionality difference
is the addition of the FoldableAsLoad & Rematerializable flags to some of the
load instructions. ARM has these flags set for them.

Evan Cheng 19dc77cec6 Fix a minor bug in two-address pass. It was missing a commute opportunity.
regB = move RCX
regA = op regB, regC
RAX  = move regA
where both regB and regC are killed. If regB is constrainted to non-compatible
physical registers but regC is not constrainted at all, then it's better to
commute the instruction.

Greg Clayton 69b582fa94 Changed:
SBValue SBFrame::LookupVar(const char *name);
To
	SBValue SBFrame::FindVariable (const char *name);

Changed:
	SBValue LookupVarInScope (const char *name, const char *scope);
to
	SBValue FindValue (const char *name, ValueType value_type);

The latter makes it possible to not only find variables (params, locals, globals, and statics), but we can also now get register sets, registers and persistent variables using the frame as the context.

Chris Lattner 7499b452c1 - Insert new instructions before DomBlock's terminator,
which is simpler than finding a place to insert in BB.
 - Don't perform the 'if condition hoisting' xform on certain
   i1 PHIs, as it interferes with switch formation.

This re-fixes "example 7", without breaking the world hopefully.

Chris Lattner 335f0e4ad4 fix two significant issues with FoldTwoEntryPHINode:
first, it can kick in on blocks whose conditions have been
folded to a constant, even though one of the edges will be
trivially folded.

second, it doesn't clean up the "if diamond" that it just 
eliminated away.  This is a problem because other simplifycfg
xforms kick in depending on the order of block visitation,
causing pointless work.

John McCall aa6d98c160 Factor out most of the extra state in a FunctionProtoType into a separate

Bill Wendling 092a7bdf9f The tLDR et al instructions were emitting either a reg/reg or reg/imm
instruction based on the t_addrmode_s# mode and what it returned. There is some
obvious badness to this. In particular, it's hard to do MC-encoding when the
instruction may change out from underneath you after the t_addrmode_s# variable
is finally resolved.

The solution is to revert a long-ago change that merged the reg/reg and reg/imm
versions. There is the addition of several new addressing modes. They no longer
have extraneous operands associated with them. I.e., if it's reg/reg we don't
have to have a dummy zero immediate tacked on to the SDNode.

There are some obvious cleanups here, which will happen shortly.

Greg Clayton 8b2fe6dcbd Modified LLDB expressions to not have to JIT and run code just to see variable
values or persistent expression variables. Now if an expression consists of
a value that is a child of a variable, or of a persistent variable only, we
will create a value object for it and make a ValueObjectConstResult from it to
freeze the value (for program variables only, not persistent variables) and
avoid running JITed code. For everything else we still parse up and JIT code
and run it in the inferior. 

There was also a lot of clean up in the expression code. I made the 
ClangExpressionVariables be stored in collections of shared pointers instead
of in collections of objects. This will help stop a lot of copy constructors on
these large objects and also cleans up the code considerably. The persistent
clang expression variables were moved over to the Target to ensure they persist
across process executions.

Added the ability for lldb_private::Target objects to evaluate expressions.
We want to evaluate expressions at the target level in case we aren't running
yet, or we have just completed running. We still want to be able to access the
persistent expression variables between runs, and also evaluate constant 
expressions. 

Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects
can now dump their contents with the UUID, arch and full paths being logged with
appropriate prefix values.

Thread hardened the Communication class a bit by making the connection auto_ptr
member into a shared pointer member and then making a local copy of the shared
pointer in each method that uses it to make sure another thread can't nuke the
connection object while it is being used by another thread.

Added a new file to the lldb/test/load_unload test that causes the test a.out file
to link to the libd.dylib file all the time. This will allow us to test using
the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else.
