[ObjCARC] Turn off ignoring unwind edges in ObjCARC when -fno-objc-arc-exception is enabled due to it's affect on correctness.

Specifically according to the semantics of ARC -fno-objc-arc-exception simply
states that it is expected that the unwind path out of a call *MAY* not release
objects. Thus we can have the situation where a release gets moved into a catch
block which we ignore when we remove a retain/release pair resulting in (even
though we assume the program is exiting anyways) the cleanup code path
potentially blowing up before program exit.

SDKROOT should only be unset/cleared for ARM builds. The first fix by Bob Wilson removed it for ARM for both configure and make, but only unset it for desktop configure, not for the make. My next fix unset/cleared it all the time. This fix only unset/clears it for ARM builds.

Since we already have this type it's a shame to keep dragging a pair of object

The Mips RDHWR (Read Hardware Register) instruction was not

using the DW_FORM_GNU_addr_index and a separate .debug_addr section which
stays in the executable and is fully linked.

Sneak in two other small changes:

a) Print out the debug_str_offsets.dwo section.
b) Change form we're expecting the entries in the debug_str_offsets.dwo
   section to take from ULEB128 to U32.

Add tests for all of this in the fission-cu.ll test.

that we now also have to ignore breakpoints

llvm-svn: 172575

isas and corresponding names from the underlying process
in a manner much quicker than the current approach.

The current approach accesses memory in the underlying
process with a random-access pattern as it walks across
the data structures associated with each isa.  This
involves a great deal of back-and-forth with debugserver,
resulting in performance problems, especially with iOS
targets.

The new approach attempts to run an expression in the
target that collects the isas and names into two large
buffers, which LLDB then collects in one shot.

handling multiple clients.  However, occasionally an
expression must be run in the service of another
expression, and in this case two parsers need to access
the same list of persistent variables.

To allow this, persistent variables now provide state
for multiple parsers, and parsers must allocate, access,
and deallocate this state by providing their own ID
(at the moment, simply the value of the "this" pointer).

into which we can emit single instructions without fixups (which is most
instructions). This is an optimization required because MCDataFragment
is prety large (240 bytes on x64), with no change in functionality.

For large programs, this reduces memory usage overhead required for bundling
by 40%.

To make the code as palatable as possible, the MCEncodedFragment interface was
further fragmented (no pun intended) and MCEncodedFragmentWithFixups is used
as the interface to work against when the user expects fixups. MCDataFragment
and MCRelaxableFragment implement this interface, while the new
MCCompactEncodedInstFragment implements MCEncodeFragment.

After discussing the refactoring with Jim and Daniel, the following changes were
made:

* All generic directive parsing is now done by AsmParser itself. The previous
  division between it and GenericAsmParser did not have clear boundaries and
  just produced unnatural code of GenericAsmParser juggling the internals of
  AsmParser through an interface. 
  The division of responsibilities is now clear: target-specific directives,
  other extensions (used by platform-specific parseres), and generic directives.
* Priority for directive parsing was reshuffled to ask extensions first and
  check the generic directives later.

No change in functionality.
