897473a28d Adjust offsets for max load instruction offsets. This is more pessimistic
than it needs to be by 1 bit but I need to finish some other things so 
that all the boundary cases will work in that situation. constpool.c
in test-suite will fail to assemble under our new internal test-suite sync
without this change.

d12cef8281 llvm-objdump: Don't print "Import table:" header if there's no import table.
If a binary does not depend on any DLL, it does not contain import table at
all. Printing the section title without contents looks wrong, so we shouldn't
print it in that case.

a034c96443 Fix parsing of .symver directive on ARM
ARM assembly syntax uses @ for a comment, execpt for the second
parameter of the .symver directive which requires @ as part of the
symbol name. This commit fixes the parsing of this directive by
adding a special case for ARM for this one argumnet.

To make the change we had to move the AllowAtInIdentifier variable
to the MCAsmLexer interface (from AsmLexer) and expose a setter for
the value.  The ELFAsmParser then toggles this value when parsing
the second argument to the .symver directive for a target that
uses @ as a comment symbol

4c831d97bf [LTO] Add a hook to map LLVM diagnostics into the clients of LTO.
Add a hook in the C API of LTO so that clients of the code generator can set
their own handler for the LLVM diagnostics.
The handler is defined like this:
typedef void (*lto_diagnostic_handler_t)(lto_codegen_diagnostic_severity_t
severity, const char *diag, void *ctxt)
- severity says how bad this is.
- diag is a string that contains the diagnostic message.
- ctxt is the registered context for this handler.

This hook is more general than the lto_get_error_message, since this function
keeps only the latest message and can only be queried when something went wrong
(no warning for instance).

070764ee85 Use a heavier hammer when --enable-libcpp is passed to bypass the tests
which catch buggy versions of libstdc++. While libc++ would pass them,
we don't actually update the state in the configure script to use libc++
when we pass --enable-libcpp, the logic for that is in the
Makefiles. So just completely skip the library test when that configure
flag is passed.

Hopefully this will be enough to fix the darwin bots at last, and thanks
to Duncan Smith for getting things set up so I can watch the bots myself
on lab.llvm.org and see any failures!

3cab648f22 [DAGCombiner] Fix a wrong check in method SimplifyVBinOp.
This fixes a regression intruced by r199135.

Revision 199135 tried to simplify part of the logic in method
DAGCombiner::SimplifyVBinOp introducing calls to method BuildVectorSDNode::isConstant().

However, that revision wrongly changed the check performed by method
SimplifyVBinOp to identify dag nodes that can be folded.
Before revision 199135, that method only tried to simplify vector binary operations
if both operands were build_vector of Constant/ConstantFP/Undef only.

After revision 199135, method SimplifyVBinop tried to
simplify also vector binary operations with only one constant operand.

This fixes the problem restoring the old behavior of SimplifyVBinOp.

9c62b5eabb Add a check to configure that the libstdc++ selected by Clang isn't
libstdc++v4.6. This is quite hard to test directly, so we test for it by
checking a known missing feature in that version that was added in v4.7.

This should prevent users from upgrading Clang but not GCC and hosting
with a too-old GCC's libstdc++ and getting strange and hard to debug
errors when we switch to C++11 by default.

Also, switch several of the macros I introduced to use AC_LANG_SOURCE
rather than AC_LANG_PROGRAM as we don't need configure's help writing
our main function (and we don't need such a function at all for most of
the tests).

MSVC on x64 requires that we create image relative symbol
references to refer to RTTI data. Seeing as how there is no way to
explicitly make reference to a given relocation type in LLVM IR, pattern
match expressions of the form &foo - &__ImageBase.

89fa06ba0f Switch-to-lookup tables: set threshold to 3 cases
There has been an old FIXME to find the right cut-off for when it's worth
analyzing and potentially transforming a switch to a lookup table.

The switches always have two or more cases. I could not measure any speed-up
by transforming a switch with two cases. A switch with three cases gets a nice
speed-up, and I couldn't measure any compile-time regression, so I think this
is the right threshold.

In a Clang self-host, this causes 480 new switches to be transformed,
and reduces the final binary size with 8 KB.

The GNU as behavior is a bit different and very strange. It will mark any

type looks more natural since gas will not mark a function if a .word is
used to output the instructions!

2a0c41756b PR 18466: Fix ARM Pseudo Expansion
When expanding neon pseudo stores, it may miss the implicit uses of sub
regs, which may cause post RA scheduler reorder instructions that
breakes anti dependency.

For example:
  VST1d64QPseudo %R0<kill>, 16, %Q9_Q10, pred:14, pred:%noreg
  will be expanded to
    VST1d64Q %R0<kill>, 16, %D18, pred:14, pred:%noreg;

An instruction that defines %D20 may be scheduled before the store by
mistake.

This patches adds implicit uses for such case. For the example above, it
emits:
  VST1d64Q %R0<kill>, 8, %D18, pred:14, pred:%noreg, %Q9_Q10<imp-use>

83ece7a499 Sanitize MCJIT remote execution
MCJIT remote execution (ChildTarget+RemoteTargetExternal) protocol was in
dire need of refactoring. It was fail-prone, had no error reporting and
implemented the same message logic on every single function.

This patch rectifies it, and makes it work on ARM, where it was randomly
failing. Other architectures shall profit from this change as well, making
their buildbots and releases more reliable.

5f33cbc414 Add FPExt option to CCValAssign::LocInfo. When generating calling-convention
promotion code, Tablegen will now select FPExt for floating point promotions
(previously it had returned AExt, which is not valid for floating point types).

Any out-of-tree targets that were relying on AExt being returned for FP
promotions will need to update their code check for FPExt instead.
