This is in preparation for adding assignments to temporaries to ensure
that the proper type checking is done.

a global is larger than 32 bytes and has fewer than 6 non-zero values in the
initializer.  Previously we'd turn something like this:

char test8(int X) {
  char str[10000] = "abc";

into a 10K global variable which we then memcpy'd from.  Now we generate:

  %str = alloca [10000 x i8], align 16
  %tmp = getelementptr inbounds [10000 x i8]* %str, i64 0, i64 0
  call void @llvm.memset.p0i8.i64(i8* %tmp, i8 0, i64 10000, i32 16, i1 false)
  store i8 97, i8* %tmp, align 16
  %0 = getelementptr [10000 x i8]* %str, i64 0, i64 1
  store i8 98, i8* %0, align 1
  %1 = getelementptr [10000 x i8]* %str, i64 0, i64 2
  store i8 99, i8* %1, align 2

Which is much smaller in space and also likely faster.

Scan the MachineFunction for DBG_VALUE instructions, and replace them with a
data structure similar to LiveIntervals. The live range of a DBG_VALUE is
determined by propagating it down the dominator tree until a new DBG_VALUE is
found. When a DBG_VALUE lives in a register, its live range is confined to the
live range of the register's value.

LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially
extended when registers are joined.

The missing half will recreate DBG_VALUE instructions from the intervals when
register allocation is complete.

The pass is disabled by default. It can be enabled with the temporary command
line option -live-debug-variables.

Check for compatible gcc, Altivec and Neon vectors before handling the
lax-vector-conversions case.  Otherwise there is no way to avoid the

definition of an Objective-C class. Unlike with C/C++ classes, we
don't have a well-defined point in Sema where Objective-C classes are
checked for completeness, nor do we need to involve Sema when
completing a class. Therefore, we take the appropriate of having the
external AST source mark a particular Objective-C class as having an
external declaration; when using one of the accessors of an
Objective-C class that has an external declaration, we request that
the external AST source fill in the Objective-C class definition.

    Don't overwhelm the expression mechanism.  Previously, there was no delay
    between successive invocations of 'expression' command.  The test suite
    run has experienced 'Resume timed out' or similar error messages.  Now we
    currently add a sleep of 1.0 second before issuing the next 'expression'
    command.

Check in an example blacklist file: blacklist.py:

"""
'blacklist' is a Python dictionary, it stores the mapping of a string describing
either a testclass or a testcase, i.e, testclass.testmethod, to the reason (a
string) it is blacklisted.

Following is an example which states that test class IntegerTypesExprTestCase
should be skipped because 'This test class crashed' and the test case
FoundationTestCase.test_data_type_and_expr_with_dsym should be skipped because
it is 'Temporarily disabled'.

blacklist = {'IntegerTypesExprTestCase': 'This test class crashed',
             'FoundationTestCase.test_data_type_and_expr_with_dsym': 'Temporarily disabled'
             }
"""

blacklist = {}

An example of invoking the test driver and specifying a blacklist file:

./dotest.py -b blacklist.py -v types

This runs the tests under 'types' directory but excludes the tests specified in
balcklist.py.

conversions. Previously, we would end up collapsing qualification
conversions into the Objective-C pointer conversion step, including
(possibly) stripping qualifiers that shouldn't be removed.

This generalizes BuildSimilarlyQualifiedPointerType() to also work on
Objective-C object pointers, then eliminates the (redundant, not
totally correct) BuildSimilarlyQualifiedObjCObjectPointerType()
function.
