Two test cases are added which reflect the next level of functionality:
constants getting moved to water areas that are out of range from the
initial placement at the end of the function and basic blocks being split to
create water when none exists that can be used. There is a bunch of this
code that is not complete and has been marked with IN_PROGRESS. I will
finish cleaning this all up during the next week or two and submit the
rest of the test cases. I have elminated some code for dealing with
inline assembly because to me it unecessarily complicates things and
some of the newer features of llvm like function attributies and builtin
assembler give me better tools to solve the alignment issues created
there. Also, for Mips16 I even have the option of not doing constant
islands in the present of inline assembler if I chose.

This change fixes Richard's testcase for r193815. Now we include non-explicit
submodules into the list of exports.
The test failed previously because:
- recursive_visibility_a1.inner is not imported (only recursive_visibility_a1 is),
- thus the 'inner' submodule is not showing up in any of the import lists,
- and because of this getExportedModules() is not returning the
correct module set -- it only considers modules that are imported.
The fix is to make Module::getExportedModules() include non-explicit submodules
into the list of exports.

When the elements are extracted from a select on vectors
or a vector select, do the select on the extracted scalars
from the input if there is only one use.

Fixed a case where on darwin, after recent compiler changes a few months ago, we could not execute dlopen() in an expression, or use "process load".
The issue was some compiler option default values changed. We now override these settings to get the old behavior back.

Cleaned up ClangUserExpression::Evaluate() to have only one variant that takes a "const EvaluateExpressionOptions& options" instead of taking many arguments.
The "--debug" option is designed to allow you to debug your expression by stopping at the first instruction (it enables --ignore-breakpoints=true and --unwind-on-error=false) and allowing you to step through your JIT code. It needs to be more integrated with the thread plan, so I am checking this in so Jim Ingham can make it happen.

Similar C code isn't caught as it seems to hit a different code path.
Also, as the check is only done for record pointers, cases involving
an overloaded operator-> are not handled either. Note that the reason
this check is done in the parser instead of Sema is not related to
having enough knowledge about the current state as it is about being
able to fix up the parser's state to be able to recover and traverse the
correct code paths.

With this patch we produce alias for cases like
template<typename T>
struct foobar {
foobar() {
}
};
template struct foobar<void>;
We just have to be careful to produce the same aliases in every TU because
of comdats.

In order to create an ObjectFile implementation that uses bitcode files, we
need to propagate the bitcode errors to the ObjectFile interface, so we need
to convert it to use the same error handling as ObjectFile: error_code.

A while ago EmitForStmt was changed to explicitly evaluate the
condition expression and create a branch instead of using
EmitBranchOnBool, so that the condition expression could be used for
some cleanup logic. The cleanup stuff has since been reorganized, and
this is no longer necessary.
In EmitCXXForRange, the evaluated condition was never used for
anything else. The logic was presumably modeled on EmitForStmt.

An initialization somehow found its way in between a comment and the
block of code the comment is about. Moving the initialization makes
this less confusing.

at some point in the past. We may have nothing more than a pc value
for this type of stack frame -- hopefully we'll have a pc and a
stop_id so we can track module loads and unloads over time and
symbolicate the pc at the correct point in time.
Also add a flag to indicate if the CFA for the frame is available
(a bit different from a CFA of LLDB_INVALID_ADDRESS) and also an
overall setting to indicate whether this is a history stack frame
or not. A history stack frame may not have a CFA, it may not have
a register context, it may not have variables, it may not have a
frame pointer or a stack pointer.

pure virtual base class and made StackFrame a subclass of that. As
I started to build on top of that arrangement today, I found that it
wasn't working out like I intended. Instead I'll try sticking with
the single StackFrame class -- there's too much code duplication to
make a more complicated class hierarchy sensible I think.

This patch should fix the test when it runs on Windows, by allowing drive
letter separator (colon) in the path. Now all LLD ELF tests passed on MSVC
2012 32-bit. Hooray!

and the move assignment for the virtual base is not trivial).

would be deleted are still declared, but are ignored by overload resolution.
Also, don't delete such members if a subobject has no corresponding move
operation and a non-trivial copy. This causes us to implicitly declare move
operations in more cases, but risks move-assigning virtual bases multiple
times in some circumstances (a warning for that is to follow).

If the sole distinction between two declarations is that one has a
__restrict qualifier then we should not consider it to be an overload.
Instead, we will consider it as an incompatible redeclaration which is
similar to how MSVC, ICC and GCC would handle it.
This fixes PR17786.
N.B. We must not mangle in __restrict into method qualifiers becase we
don't allow overloading between such declarations anymore. To do
otherwise would be a violation of the Itanium ABI.
