The reference manual defines only 5 permitted values for the immediate field of the "hint" instruction:
1. nop (imm == 0)
2. yield (imm == 1)
3. wfe (imm == 2)
4. wfi (imm == 3)
5. sev (imm == 4)

Therefore, restrict the permitted values for the "hint" instruction to 0 through 4.

This was slightly tricky because BlockDecls don't currently store an
inferred return type. However, we can rely on the fact that blocks with
inferred return types will have return statements that match the inferred
type.

Summary:
Added BreakableLineComment, moved common code from
BreakableBlockComment to newly added BreakableComment. As a side-effect of the
rewrite, found another problem with escaped newlines and had to change
code which removes trailing whitespace from line comments not to break after
this patch.

VerifyDiagnosticConsumer previously would not check that the diagnostic and
its matching directive referenced the same source file.  Common practice was
to create directives that referenced other files but only by line number,
and this led to problems such as when the file containing the directive
didn't have enough lines to match the location of the diagnostic in the
other file, leading to bizarre file formatting and other oddities.

This patch causes VerifyDiagnosticConsumer to match source files as well as
line numbers.  Therefore, a new syntax is made available for directives, for
example:

// expected-error@file:line {{diagnostic message}}

This extends the @line feature where "file" is the file where the diagnostic
is generated.  The @line syntax is still available and uses the current file
for the diagnostic.  "file" can be specified either as a relative or absolute
path - although the latter has less usefulness, I think!  The #include search
paths will be used to locate the file and if it is not found an error will be
generated.

The new check is not optional: if the directive is in a different file to the
diagnostic, the file must be specified.  Therefore, a number of test-cases
have been updated with regard to this.

This closes out PR15613.

IRMemoryMap rather than through its own memory
abstraction.  This considerably simplifies the
code, and makes it possible to run the
IRInterpreter multiple times on an already-parsed
expression in the absence of a ClangExpressionDeclMap.

Changes include:

  - ClangExpressionDeclMap's interface methods
    for the IRInterpreter now take IRMemoryMap
    arguments.  They are not long for this world,
    however, since the IRInterpreter will soon be
    working with materialized variables.

  - As mentioned above, removed the Memory class
    from the IR interpreter altogether.  It had a
    few functions that remain useful, such as
    keeping track of Values that have been placed
    in memory, so I moved those into methods on
    InterpreterStackFrame.

  - Changed IRInterpreter to work with lldb::addr_t
    rather than Memory::Region as its primary
    currency.

  - Fixed a bug in the IRMemoryMap where it did not
    report correct address byte size and byte order
    if no process was present, because it was using
    Target::GetDefaultArchitecture() rather than
    Target::GetArchitecture().

  - Made IRMemoryMap methods clear the Errors they
    receive before running.  Having to do this by
    hand is just annoying.

The testsuite seems happy with these changes, but
please let me know if you see problems (especially
in use cases without a process).

In the classical (non -polly-codegen-scev) mode, we assume that we can always
recreate PHI nodes during code generation. This is not true. We can only
reconstruct them from the polyhedral information, in case the entire loop of the
PHI node is part of the SCoP and consequently the PHI node was translated in
the polyhedral description.

We now support regions with multiple entries and multiple exits natively.
Regions are not needed to be simplified to single entry and single exit.

We need to XFAIL two test cases as this change increases the scop coverage
and uncoveres two failures in the independent blocks pass. The first failure
will be fixed in a subsequent commit, the second one is in the non-default
-polly-codegen-scev mode and still needs to be fixed.

We currently emit an error message when you try to use thread local
storage on targets that don't support it and testing C++11 thread
locals will trip this. We don't want to xfail the test for all darwin
hosts so add a quick hack to check for darwin10 and disable the
test based on that. Only checking darwin10 because anything earlier
is really old and I don't have a list of what other hosts don't
support tls handy.
