Fix BNF nits in TableGen language reference.
Summary:
In the course of writing an experimental ANTLR grammar based on this
document, I found three errors in the documented BNF:
SimpleValues of dag type are allowed to have no operands at all after
the initial DagArg specifying the operator. For example, the value
(outs) is extremely common in backends; an example in the test suite
is test/TableGen/AsmVariant.td line 30. But the BNF doesn't allow
DagArgList to expand to the empty string (it must contain at least one
DagArg), and therefore the DagArgList specifying the operands in the
dag-shaped production for SimpleValue should be optional.
In the production for BodyItem with a 'let' and an optional RangeList,
the RangeList should have braces around it if it's present, matching
code such as "let E{7-0} = ..." on test/TableGen/BitsInit.td line 42.
Those braces aren't included in the RangeList nonterminal itself, so
instead they need to be part of the optional segment of the BodyItem
production.
Finally, the identifier after 'defm' should be optional. Again, this
is very common in the real back end .td files; an example in the test
suite is in test/TableGen/defmclass.td line 49.

[PatternMatch] allow undef elements when matching a vector zero
This is the last step in getting constant pattern matchers to allow
undef elements in constant vectors.
I'm adding a dedicated m_ZeroInt() function and building m_Zero() from

directly when there's no need to match pointers, but I'm leaving that
efficiency optimization as a follow-up step because it's not always
clear when that's ok.
There are just enough icmp folds in InstSimplify that can be used for
integer or pointer types, that we probably still want a generic m_Zero()
for those cases. Otherwise, we could eliminate it (and possibly add a
m_NullPtr() as an alias for isa<ConstantPointerNull>()).
We're conservatively returning a full zero vector (zeroinitializer) in
InstSimplify/InstCombine on some of these folds (see diffs in InstSimplify),

able to propagate an undef lane instead. One test where this happens is

Summary:
`llvm-bcanalyzer` prints out the stream type of the file it is
analyzing. If the file begins with the LLVM IR magic number, it reports
a stream type of "LLVM IR". However, any other bitstream format is
reported as "unknown".
Add some checks for two other common bitstream formats: Clang AST
files, which begin with 'CPCH', and Clang serialized diagnostics, which
begin with 'DIAG'.

The current way that the lit configuration is generated for the LLDB
tests that run using dotest causes cmake to fail when using a generator
which supports multiple configurations (such as Visual Studio). The
failure is because file GENERATE will create a file *per possible
configuration* resulting in the same lit configuration file being
overwritten multiple times.

of the configurations and can be used for any configuration.

[libclang] Fix LibclangReparseTest.FileName when TMPDIR is set to a symlink
Fix testing of clang_File_tryGetRealPathName() in
LibclangReparseTest.FileName when executing in an environment which has
TMPDIR set to a symbolic link that points to an actual directory. The
test would fail because the name returned by
clang_File_tryGetRealPathName() has the symlink resolved but the test
compared it to the original filename of a temporary file.
The patch addresses the problem by checking only that the value returned
by clang_File_tryGetRealPathName() ends with "main.cpp".
Additionally, the patch makes the previous assertion in the test that
checks result of clang_getFileName() stricter. It newly verifies that
the name returned by the function is exactly same as what was given to
clang_parseTranslationUnit()/clang_getFile().
