Renato Golin dfc5d1ffab [AArch64] Adding a TargetParser for AArch64
There's already a ARMTargetParser,now adding a similar one for aarch64.
so we can use it to do ARCH/CPU/FPU parsing in clang and llvm, instead of
string comparison.

Patch by Jojo Ma.

Dan Gohman d530f68d45 [WebAssembly] Put __stack_pointer in the offset field of loads and stores.
Instead of this:

i32.const       $push10=, __stack_pointer
i32.load        $push11=, 0($pop10)

Emit this:

i32.const       $push10=, 0
i32.load        $push11=, __stack_pointer($pop10)

It's not currently clear which is better, though there's a chance the second
form may be better at overall compression. We can revisit this when we have
more data; for now it makes sense to make PEI consistent with isel.

Haicheng Wu 90a55651e6 [MBP] Factor out the optimizations on branch conditions and unanalyzable branches. NFCI.
The benefits of this patch are

-- We call AnalyzeBranch() to optimize unanalyzable branches, but the result of
   AnalyzeBranch() is not used. Now the result is useful.

-- Before the layout of all the MBBs is set, the result of AnalyzeBranch() is
   not correct and needs to be fixed before using it to optimize the branch
   conditions. Now this optimization is called after the layout, the code used
   to fix the result of AnalyzeBranch() is not needed.

-- The branch condition of the last block is not optimized before. Now it is
   optimized.

David Blaikie c53e18d93a DWARF: Omit DW_AT_APPLE attributes (except ObjC ones) when not targeting LLDB
These attributes aren't used by other debuggers (& may be confused with
other DWARF extensions) so they just waste space (about 1.5% on .dwo
file size on a random large program I tested).

We could remove the ObjC property ones too, but I figured they were
probably more necessary when trying to understand ObjC (I could be wrong
though) & so any debugger interested in working with ObjC would use
them, perhaps? (also, there are some legacy tests in Clang that test for
them - making it one of those annoying cross-project commits and/or
cleanup to refactor those tests)
