llvm-objdump: Print x64 unwind info in executable.
The original code does not work correctly on executable files because the
code is written in such a way that only object files are assumed to be given
to llvm-objdump.
Contents of RuntimeFunction are different between executables and objects. In
executables, fields in RuntimeFunction have actual addresses to unwind info
structures. On the other hand, in object files, the fields have zero value,
but instead there are relocations pointing to the fields, so that Linker will
fill them at link-time.
So, when we are reading an object file, we need to use relocation info to
find the location of unwind info. When executable, we should just look at the
values in RuntimeFunction.

[AArch64] This is a work in progress to provide a machine description
for the Cortex-A53 subtarget in the AArch64 backend.
This patch lays the ground work to annotate each AArch64 instruction
(no NEON yet) with a list of SchedReadWrite types. The patch also
provides the Cortex-A53 processor resources, maps those the the default
SchedReadWrites, and provides basic latency. NEON support will be added
in a subsequent patch with proper forwarding logic.
Verification was done by setting the pre-RA scheduler to linearize to
better gauge the effect of the MIScheduler. Even without modeling the
forward logic, the results show a modest improvement for Cortex-A53.

DWARF discriminators are used to distinguish multiple control flow paths

basic block boundaries will share the same debug location.
This pass detects this situation and creates a new lexical scope to one
of the two instructions. This lexical scope is a child scope of the

Remove extra truncs/exts around i32 bit operations on PPC64
This generalizes the code to eliminate extra truncs/exts around i1 bit
operations to also do the same on PPC64 for i32 bit operations. This eliminates
a fairly prevalent code wart:
int foo(int a) {
return a == 5 ? 7 : 8;
}
On PPC64, because of the extension implied by the ABI, this would generate:
cmplwi 0, 3, 5
li 12, 8
li 4, 7
isel 3, 4, 12, 2
rldicl 3, 3, 0, 32
blr
where the 'rldicl 3, 3, 0, 32', the extension, is completely unnecessary. At
least for the single-BB case (which is all that the DAG combine mechanism can
handle), this unnecessary extension is no longer generated.
