117de489a0 [asan] added a flag -mllvm asan-short-64bit-mapping-offset=1 (0 by default)
This flag makes asan use a small (<2G) offset for 64-bit asan shadow mapping.
On x86_64 this saves us a register, thus achieving ~2/3 of the
zero-base-offset's benefits in both performance and code size.

Thanks Jakub Jelinek for the idea.

716d26b2ce AArch64: fix build on some MSVC versions
This does two things:

It removes a call to abs() which may have "long long" parameter on Windows,
which is not necessarily available in C++03.

It also corrects the signedness of Amount, which was relying on
implementation-defined conversions previously.

Code was already tested (albeit in an implemnetation defined way) so no extra
tests.

77b1c9cf57 AArch64: Simplify logic in deciding whether bfi is valid
Previous code had a confusing comment which was mostly an implementation
detail. This condition corresponds to "lsb up to register width" and "width not
ridiculous".

b516186386 Make use of DiagnosticType to provide better AArch64 diagnostics.
This gives a DiagnosticType to all AsmOperands in sight. This replaces all
"invalid operand" diagnostics with something more specific. The messages given
should still be sufficiently vague that they're not usually actively misleading
when LLVM guesses your instruction incorrectly.

8597c14e9b Add support for updating LiveIntervals to MachineBasicBlock::SplitCriticalEdge().
This is currently a bit hairier than it needs to be, since depending on where the
split block resides the end ListEntry of the split block may be the end ListEntry
of the original block or a new entry. Some changes to the SlotIndexes updating
should make it possible to eliminate the two cases here.

This also isn't as optimized as it could be. In the future Liveinterval should
probably get a flag that indicates whether the LiveInterval is within a single
basic block. We could ignore all such intervals when splitting an edge.

b29ce26ea6 Add support for printing out the attribute groups.
This emits the attribute groups that are used by the functions. (It currently
doesn't print out return type or parameter attributes within attribute groups.)

Note: The functions still retrieve their attributes from the "old" bitcode
format (using the deprecated 'Raw()' method). This means that string attributes
within an attribute group will not show up during a disassembly. This will be
addressed in a future commit.

f64c889cc9 Revert "Rename LLVMContext diagnostic handler types and functions."
This reverts my commit 171047. Now that I've removed my misguided attempt to
support backend warnings, these diagnostics are only about inline assembly.
It would take quite a bit more work to generalize them properly, so I'm
just reverting this.

da20ea696d BBVectorize: Make the bookkeeping to support full cycle checking less expensive
By itself, this does not have much of an effect, but only because in the default
configuration the full cycle checks are used only for small problem sizes.
This is part of a general cleanup of uses of iteration over std::multimap
ranges only for the purpose of checking membership.

092e5e7566 Currently, codegen may spent some time in SDISel passes even if an entire
function is successfully handled by fast-isel. That's because function
arguments are *always* handled by SDISel. Introduce FastLowerArguments to
allow each target to provide hook to handle formal argument lowering.

As a proof-of-concept, add ARMFastIsel::FastLowerArguments to handle
functions with 4 or fewer scalar integer (i8, i16, or i32) arguments. It
completely eliminates the need for SDISel for trivial functions.

b7cfac32f3 Add support for updating LiveIntervals to PHIElimination. If LiveIntervals are
present, it currently verifies them with the MachineVerifier, and this passed
all of the test cases in 'make check' (when accounting for existing verifier
errors). There were some assertion failures in the two-address pass, but they
also happened on code without phis and look like they are caused by different
kill flags from LiveIntervals.

The only part that doesn't work is the critical edge splitting heuristic,
because there isn't currently an efficient way to update LiveIntervals after
splitting an edge. I'll probably start by implementing the slow fallback and
test that it works before tackling the fast path for single-block ranges. The
existing code that updates LiveVariables is fairly slow as it is.

There isn't a command-line option for enabling this; instead, just edit
PHIElimination.cpp to require LiveIntervals.

0b77866f93 TEMPORARY SYNTAX CHANGE!
The original syntax for the attribute groups was ambiguous. For example:

    declare void @foo() #1
    #0 = attributes { noinline }

The '#0' would be parsed as an attribute reference for '@foo' and not as a
top-level entity. In order to continue forward while waiting for a decision on
what the correct syntax is, I'm changing it to this instead:

     declare void @foo() #1
     attributes #0 = { noinline }

Repeat: This is TEMPORARY until we decide what the correct syntax should be.
