convenience variables (from the ExecutionContext) each time
it is entered: lldb.debugger, lldb.target, lldb.process,
lldb.thread, lldb.frame.
If a frame (or thread, process, etc) does not currently exist,
the variable contains the Python value 'None'.

Register coalescing can sometimes create live ranges that end in the middle of a
basic block without any killing instruction. When SplitKit detects this, it will
repair the live range by shrinking it to its uses.
Live range splitting also needs to know about this. When the range shrinks so
much that it becomes allocatable, live range splitting fails because it can't
find a good split point. It is paranoid about making progress, so an allocatable
range is considered an error.
The coalescer should really not be creating these bad live ranges. They appear
when coalescing dead copies.

checking both the source and the destination operands, renaming the
warning group to -Wnon-pod-memaccess and tweaking the diagnostic text

max(a,b) >= a -> true. According to my super-optimizer, these are
by far the most common simplifications (of the -instsimplify kind)
that occur in the testsuite and aren't caught by -std-compile-opts.

parameters on the floor in certain cases:
class X {
template <typename T> friend typename A<T>::Foo;
};
This was parsed as a *non* template friend declaration some how, and
received an ExtWarn. Fixing the parser to actually provide the template
parameters to the freestanding declaration parse triggers the code which
specifically looks for such constructs and hard errors on them.
Along the way, this prevents us from trying to instantiate constructs
like the above inside of a outer template. This is important as loosing
the template parameters means we don't have a well formed declaration
and template instantiation will be unable to rebuild the AST. That fixes
a crash in the GCC test suite.

Change one test sequence to detect the '** End Stop Hooks **' marker emitted by the
stop hooks mechanism and check for whether the 'expr ptr' stop-hook has been run.
Also, change the TestBase.tearDown() to wait for 2 seocnds before forcefully kill
the pexpect-spawned child lldb process.

model constants which can be added to base registers via add-immediate
instructions which don't require an additional register to materialize
the immediate.

to spawn an lldb child command. The test is not "correct" in that the '** Stop Hooks **'
message emitted by the Target implementation is invoked asynchronously and is using a separate:
CommandReturnObject result;
command return object that what the driver passes to the normal command interpreter loop.
But it can help test our output serialization work.
I need to modify the test case later to maybe only test that "-o 'expr ptr'" option does indeed work.

Changed the integer type that range-based for-loops used. Switched to pointer difference type, which satisfies the new assert in IntegerLiteral.
