Jakob Stoklund Olesen 7b73528064 Add assertions to verify that the new interval is clear of the interference.
If these inequalities don't hold, we are creating a live range split that won't
allocate.

Eric Christopher 2dfbd7e0c1 Rewrite how the indirect call bonus is handled. This now works by:
a) Making it a per call site bonus for functions that we can move from
indirect to direct calls.
b) Reduces the bonus from 500 to 100 per call site.
c) Subtracts the size of the possible newly inlineable call from the
bonus to only add a bonus if we can inline a small function to devirtualize
it.

Also changes the bonus from a positive that's subtracted to a negative
that's added.

Fixes the remainder of rdar://8546196 by reducing the object file size
after inlining by 84%.

Johnny Chen 6e2acff0be Add EmulateInstructionARM::EmulateIT() to the g_thumb_opcodes table,
to represent the the 'If Then' instruction which makes up to four following
instructions (the IT block)conditional.

David Greene bdd481507a [AVX] Add some utilities to insert and extract 128-bit subvectors.
This allows us to easily support 256-bit operations that don't have
native 256-bit support.  This applies to integer operations, certain
types of shuffles and various othher things.

Jakob Stoklund Olesen e8ac8e93a1 Apparently, it is possible for a block with a landing pad successor to have no calls.
In that case we simply ignore the landing pad and split live ranges before the
first terminator.

Jakob Stoklund Olesen 80a2878b5d Be more accurate about live range splitting at the end of blocks.
If interference reaches the last split point, it is effectively live out and
should be marked as 'MustSpill'.

This can make a difference when the terminator uses a register. There is no way
that register can be reused in the outgoing CFG bundle, even if it isn't live
out.

Jason W Kim d2e2f56c36 Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.
(yes, this is different from R_ARM_CALL)

- Adds a new method getARMBranchTargetOpValue() which handles the
  necessary distinction between the conditional and unconditional br/bl
  needed for ARM/ELF

At least for ARM mode, the needed fixup for conditional versus unconditional
br/bl is identical, but the ARM docs and existing ARM tools expect this
reloc type...

Added a few FIXME's for future naming fixups in ARMInstrInfo.td

Jakob Stoklund Olesen 096bd8837f Add LiveIntervals::getLastSplitPoint().
A live range cannot be split everywhere in a basic block. A split must go before
the first terminator, and if the variable is live into a landing pad, the split
must happen before the call that can throw.

Jakob Stoklund Olesen fefe6ebc73 Verify that one of the ranges produced by region splitting is allocatable.
We should not be attempting a region split if it won't lead to at least one
directly allocatable interval. That could cause infinite splitting loops.

Greg Clayton 768f2809f2 Added the start of platform configuration designed for internal LLDB use.
Internal use means for compiling the LLDB debug engine and plug-ins, but it
should never make it into the public API.

Since we don't currently have a configuration script that detects avaiable
functionality in the LLDB build system, we are hard coding #define values
in the host specific "Config.h" files. 

#define values in these Config.h header files should set the value to zero or
one:

#define LLDB_CONFIG_TERMIOS_SUPPORTED 1

#define LLDB_CONFIG_OTHER 0

Then any code in the LLDB engine should check the availability using:

#if LLDB_CONFIG_TERMIOS_SUPPORTED
....
#endif

Eventually the contents of the host specific Config.h files will be auto
generated, but for now they will be hard coded. Any LLDB_CONFIG_XXXX items
that are added should be added to all Config.h files and set to either zero
or one.

One (stepout.patch) to fix a problem in ThreadPlanStepOut.cpp. There is an erroneous semi colon at end of an if statement that make the condition useless (if body is empty).

Douglas Gregor a522693f66 Improve our handling of the current instantiation for qualified
id-expression, e.g., 

  CurrentClass<T>::member

Previously, if CurrentClass<T> was dependent and not complete, we
would treat it as a dependent-scoped declaration reference expression,
even if CurrentClass<T> referred to the current instantiation.

Fixes PR8966 and improves type checking of templates.

harmless C++0x extension.

Andrew Trick d0548ae750 Introducing a new method of tracking register pressure. We can't
precisely track pressure on a selection DAG, but we can at least keep
it balanced. This design accounts for various interesting aspects of
selection DAGS: register and subregister copies, glued nodes, dead
nodes, unused registers, etc.

Added SUnit::NumRegDefsLeft and ScheduleDAGSDNodes::RegDefIter.

Note: I disabled PrescheduleNodesWithMultipleUses when register
pressure is enabled, based on no evidence other than I don't think it
makes sense to have both enabled.
