John McCall 4e81961a1e Fix the computation of alignment for fields of packed+aligned structs. 
Part of the fix for PR8413.

Greg Clayton 4dc72284b2 Fixed the async packets (packets that need to be sent to the GDB server 
while the inferior is running) to be fast. The previous code would always
cause the sender to timeout, yet still return success due to the way we
were waiting for a value (incorrect value) to change. Now the ProcessGDBRemote
plug-in has a public and private "is running" predicate. This allows things
that need to send async packets to interrupt and wait for the private "is running"
state to be flipped to false, and then resume quickly with no timeout.

Anders Carlsson 7c812f5a99 When instantiating member functions, propagate whether the member function is marked 'final' and 'override'. 
Also, call CheckOverrideControl when instantiating member functions.

Andrew Trick 2cd1f0beb6 Selection DAG scheduler register pressure heuristic fixes. 
Added a check for already live regs before claiming HighRegPressure.
Fixed a few cases of checking the wrong number of successors.
Added some tracing until these heuristics are better understood.

Jakob Stoklund Olesen 4060abb4b9 Check that a live range exists before shortening it. This fixes PR8989. 
The live range may have been deleted earlier because of rematerialization.

Greg Clayton 16b2d2bf19 Made the DWARF + debug map symbol file parser be much more efficient when it isn't 
going to actually be used as the symbol file plug-in by looking only for suitable
N_OSO symbols and avoiding sorting function (N_FUN) and global/static (N_GSYM/N_STSYM)
symbols when there are no suitable N_OSO objects.

Rafael Espindola 9e976dcce8 Fix PR8884 by skipping transparent contexts. The test is for LikageSpec. I 
failed to find a case where an enum context would make a difference, but
found PR9007 on the way.

Jim Ingham 77787033b9 Back up both the register AND the stop state when calling functions. 
Set the thread state to "bland" before calling functions so they don't 
  inherit the pending signals and die.

Douglas Gregor 2bbfba0f0c When building a user-defined conversion sequence, keep track of the 
declaration that name lookup actually found, so that we can use it for
access checking later on. Fixes <rdar://problem/8876150>.

with an invalid type then split the result and perform the overflow check
normally.

Jakob Stoklund Olesen 509089f5b6 Don't accidentally leave small gaps in the live ranges when leaving the active 
interval after an instruction. The leaveIntvAfter() method only adds liveness
from the instruction's boundary index to the inserted copy.

Ideally, SplitKit should be smarter about this, perhaps by combining useIntv()
and leaveIntvAfter() into one method that guarantees continuity.

Douglas Gregor eecc6bc388 Variadic templates are fully implemented. 
Turn on the __has_feature switch for variadic templates, document
their completion, and put the ExtWarn into the c++0x-extensions
warning group.

Jakob Stoklund Olesen 9fb04015ff Implement RAGreedy::splitAroundRegion and remove loop splitting. 
Region splitting includes loop splitting as a subset, and it is more generic.
The splitting heuristics for variables that are live in more than one block are
now:

1. Try to create a region that covers multiple basic blocks.
2. Try to create a new live range for each block with multiple uses.
3. Spill.

Steps 2 and 3 are similar to what the standard spiller is doing.

Douglas Gregor b25d8c3af4 Downgrade the "variadic templates are a C++0x feature" error to an 
ExtWarn. We want variadic templates to be usable in libc++/libstdc++
headers even when we're in C++98/03 mode, since it's the only clean
way to implement TR1 <functional>.
