alongside DIEBlock and replace uses accordingly. Use DW_FORM_exprloc
in DWARF4 and later code. Update testcases.
Adding a DIELoc instead of using extra forms inside DIEBlock so
that we can keep location expressions separate from other uses. No
direct use at the moment, however, it's not a lot of code and
using a separately named class keeps it somewhat more obvious
what's going on in various locations.

The Linux kernel defines empty macros for compatibility with ARM UAL syntax.
The comma after the name is optional, and if present can be safely lexed. This
improves compatibility with the GNU assembler.

ProcessElfCore::ParseThreadContextsFromNoteSegment was leaking
ThreadData for each ELF note found in core file. We now allocate it
only once and use std::unique_ptr to ensure it is always being freed.
While at it make ParseFreeBSDThrMisc and ParseFreeBSDPrStatus take
ThreadData by reference, rather than pointer, since those arguments are
not optional.
Patch by Piotr Rak.

This adds a partial implementation of the .arch_extension directive to the
integrated ARM assembler. There are a number of limitations to this
implementation arising from the target backend support rather than the
implementation itself. Namely, iWMMXT (v1 and v2), Maverick, and XScale support
is not present in the ARM backend. Currently, there is no check for A-class
only (needed for virt), and no ARMv6k detection (needed for os and sec). The
remainder of the extensions are fully supported.

This broke in r185459 while TLS support was being generalized to handle
non-symbol TLS representations.
I thought about/tried having an enum rather than a bool to track the
TLS-ness of the address table entry, but namespaces and naming seemed
more hassle than it was worth for only one caller that needed to specify
this.

During LSR of one loop we can run into a situation where we have to expand the
start of a recurrence of a loop induction variable in this loop. This start
value is a value derived of the induction variable of a preceeding loop. SCEV
has cannonicalized this value to a different recurrence than the recurrence of
the preceeding loop's induction variable (the type and/or step direction) has
changed). When we come to instantiate this SCEV we created a second induction
variable in this preceeding loop. This patch tries to base such derived
induction variables of the preceeding loop's induction variable.
This helps twolf on arm and seems to help scimark2 on x86.

1. CHECK-NOT-LABEL is not valid FileCheck.
2. This test would not trigger the CHECK-NOT-LABEL even if 'interface' is
replaced with 'struct'.

This seems like a more straightforward approach for instantiating the
appropriate RegisterContext* class, made possible by Michael Sartain's
cleanup of the POSIX RegisterContext class hierarchy in r190647.
Better (user-facing) error handling is still needed.

When a function has a single counter, we will offset the pointer by 1 when
parsing the next function. If a function has multiple counters, we are
okay after skipping rest of the counters.

Revert the spirit of r199857 - a convincing case can be made that overriding a summary's format markers behind its back is not the right thing to do
This commit reverts the behavior of the code to the previous model, and changes the test case to validate the opposite of what it was validating before

Some lines intended to be used for testing x86_64 ABI compatibility were
not firing because lines were annotated with the wrong FileCheck prefix:
X64 vs 64

Type units will share the statement list of their defining compile unit.
This is a tradeoff that reduces .o debug info size at the cost of some
linked debug info size (since the contents of those string tables won't
be deduplicated along with the type unit) which seems right for now.

These types have an out of line virtual function each (emitHeader at
least) so they won't have weak vtables - no need for more than that.

This probably also addresses the FIXME in the fission case regarding
multiple compile units, though I haven't tested that.
This code still confuses me (the literal zero offset makes little sense,
the limitations surrounding asm output I'm not sure about either - but
perhaps we should just always emit one line table? Or should we not rely
on .loc/.file even in assembly so we can produce the same output between
asm and object output?) but this maintains the existing functionality.

This should be a small build time improvement in general and fixes
the build on OS X with -DBUILD_SHARED_LIBS=ON.
The issue is that not all users are including GenericDomTreeConstruction.h,
causing undefined references when ld64 managed to hide the
linkonce_odr symbols.

For some reason we have two bits of code handling this printing:
lib/AST/Decl.cpp: OS << "<anonymous namespace>";
lib/AST/TypePrinter.cpp: OS << "<anonymous namespace>::";
it would be nice if we only had one...
