79e3fb53d6 Bug 18228 - Fix accepting bitcasts between vectors of pointers with a
different number of elements.

Bitcasts were passing with vectors of pointers with different number of
elements since the number of elements was checking
SrcTy->getVectorNumElements() == SrcTy->getVectorNumElements() which
isn't helpful. The addrspacecast was also wrong, but that case at least
is caught by the verifier. Refactor bitcast and addrspacecast handling
in castIsValid to be more readable and fix this problem.

3cbfa1617f Add an inalloca flag to allocas
Summary:
The only current use of this flag is to mark the alloca as dynamic, even
if its in the entry block.  The stack adjustment for the alloca can
never be folded into the prologue because the call may clear it and it
has to be allocated at the top of the stack.

bc8569d0c0 Debug Info: update testing cases to specify the debug info version number.
We are going to drop debug info without a version number or with a different

different debug info metadata format.

Make tests more robust by removing hard-coded metadata numbers in CHECK lines.

6e3cd0ebe2 Debug Info: add an identifier field to DICompositeType.
DICompositeType will have an identifier field at position 14. For now, the
field is set to null in DIBuilder.
For DICompositeTypes where the template argument field (the 13th field)
was optional, modify DIBuilder to make sure the template argument field is set.
Now DICompositeType has 15 fields.

Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode.
Update verifier to check that DICompositeType has 15 fields and the last
field is null or a MDString.

Update testing cases to include an extra field for DICompositeType.
The identifier field will be used by type uniquing so a front end can
genearte a DICompositeType with a unique identifer.

24ec2e5a72 [tests] Cleanup initialization of test suffixes.
- Instead of setting the suffixes in a bunch of places, just set one master
   list in the top-level config. We now only modify the suffix list in a few
   suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py).

 - Aside from removing the need for a bunch of lit.local.cfg files, this enables
   4 tests that were inadvertently being skipped (one in
   Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and
   CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been
   XFAILED).

 - This commit also fixes a bunch of config files to use config.root instead of
   older copy-pasted code.

eaff2d55a9 Preserve address space of forward-referenced global variables in the LL parser
Before, the parser would assert on the following code:

@a2 = global i8 addrspace(1)* @a
@a = addrspace(1) global i8 0

because the type of @a was "i8*" instead of "i8 addrspace(1)*" when parsing
the initializer for @a2.

2333e29be4 Relax the restrictions on vector of pointer types, and vector getelementptr.
Previously in a vector of pointers, the pointer couldn't be any pointer type,
it had to be a pointer to an integer or floating point type.  This is a hassle
for dragonegg because the GCC vectorizer happily produces vectors of pointers
where the pointer is a pointer to a struct or whatever.  Vector getelementptr
was restricted to just one index, but now that vectors of pointers can have
any pointer type it is more natural to allow arbitrary vector getelementptrs.
There is however the issue of struct GEPs, where if each lane chose different
struct fields then from that point on each lane will be working down into
unrelated types.  This seems like too much pain for too little gain, so when
you have a vector struct index all the elements are required to be the same.

1de43ede89 Fix the remaining TCL-style quotes found in the testsuite. This is
another mechanical change accomplished though the power of terrible Perl
scripts.

I have manually switched some "s to 's to make escaping simpler.

While I started this to fix tests that aren't run in all configurations,
the massive number of tests is due to a really frustrating fragility of
our testing infrastructure: things like 'grep -v', 'not grep', and
'expected failures' can mask broken tests all too easily.

Essentially, I'm deeply disturbed that I can change the testsuite so
radically without causing any change in results for most platforms. =/

49589f0d0e Convert the uses of '|&' to use '2>&1 |' instead, which works on old
versions of Bash. In addition, I can back out the change to the lit
built-in shell test runner to support this.

This should fix the majority of fallout on Darwin, but I suspect there
will be a few straggling issues.

4177e6fff5 Convert all tests using TCL-style quoting to use shell-style quoting.
This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.

Finally, the test suite runs 33% faster on Linux now. ;]

563add96ce Make tests which first provide a negative assertion via 'not', then
a pipeline, and then a positive assertion via grep, use two RUN lines
instead.

Supporting these complex ideas of 'success' and 'failure' across
multiple stages of a pipeline is brittle in the shell world, and would
block switching to ShTest format; it only worked due to contrivances
introduced by the TclTest format.

Writing this as two separate RUN lines seems clearer in any event.

This is another step toward completely removing TclTests from lit.

ce718ff9f4 Extend the IL for selecting TLS models (PR9788)
This allows the user/front-end to specify a model that is better
than what LLVM would choose by default. For example, a variable
might be declared as

  @x = thread_local(initialexec) global i32 42

if it will not be used in a shared library that is dlopen'ed.

If the specified model isn't supported by the target, or if LLVM can
make a better choice, a different model may be used.

2106badea3 Add an explicit test of the auto-upgrade functionality for the new
intrinsic syntax.

Now that this is explicitly covered, I plan to upgrade the existing test
suite to use an explicit immediate. Note that I plan to specify 'true'
in most places rather than the auto-upgraded value as that is the far
more common value to end up here as that is the value coming from GCC's
builtins. The only place I'm likely to put a 'false' in is when testing
