The "run" and "r" aliases were for gdb compatability, so make then do what GDB does by default: launch in a shell.

For those that don't want launching with a shell by default, add the following to your ~/.lldbinit file:

command unalias run
command unalias r
command alias r process launch --
command alias run process launch --

Jakob Stoklund Olesen 589c6eb95c Remove -join-physregs from the test suite.
This option has been disabled for a while, and it is going away so I can
clean up the coalescer code.

The tests that required physreg joining to be enabled were almost all of
the form "tiny function with interference between arguments and return
value". Such functions are usually inlined in the real world.

The problem exposed by phys_subreg_coalesce-3.ll is real, but fairly
rare.

Sean Callanan 4407880666 I have updated Clang to include support for Objective-C
boxed expressions returning numbers and strings.

I also added boxed expressions to our testcases, and
enabled boxed expressions when libarclite is linked into
the inferior.

Douglas Gregor 0bf70f4be8 A selector match between two Objective-C methods does *not* guarantee
that the methods have the same number of parameters, although we
certainly assumed this in many places. Objective-C can be insane
sometimes. Fixes <rdar://problem/11460990>.

Kevin Enderby f1b225d0e0 Fix the encoding of the armv7m (MClass) for MSR APSR writes which was missing
the 0b10 mask encoding bits.  Make MSR APSR writes without a _<bits> qualifier
an alias for MSR APSR_nzcvq even though ARM as deprecated it use.  Also add
support for suffixes (_nzcvq, _g, _nzcvqg) for APSR versions.  Some FIXMEs in
the code for better error checking when versions shouldn't be used.

Jim Ingham 4a94c91077 If we notice that a module with a given file path is replaced by another with the same file
path on rerunning, evict the old module from the target module list, inform the breakpoints
about this so they can do something intelligent as well.

Andrew Trick 2202577d80 misched: Added 3-level regpressure back-off.
Introduce the basic strategy for register pressure scheduling.

1) Respect target limits at all times.

2) Indentify critical register classes (pressure sets).
   Track pressure within the scheduled region.
   Avoid increasing scheduled pressure for critical registers.

3) Avoid exceeding the max pressure of the region prior to scheduling.

Added logic for picking between the top and bottom ready Q's based on
regpressure heuristics.

Status: functional but needs to be asjusted to achieve good results.

Jakob Stoklund Olesen c3553ffc70 Never clear <undef> flags on already joined copies.
RegisterCoalescer set <undef> flags on all operands of copy instructions
that are scheduled to be removed. This is so they won't affect
shrinkToUses() by introducing false register reads.

Make sure those <undef> flags are never cleared, or shrinkToUses() could
cause live intervals to end at instructions about to be deleted.

This would be a lot simpler if RegisterCoalescer could just erase joined
copies immediately instead of keeping all the to-be-deleted instructions
around.

This fixes PR12862. Unfortunately, bugpoint can't create a sane test
case for this. Like many other coalescer problems, this failure depends
of a very fragile series of events.

Argyrios Kyrtzidis 3d6439517c [arcmt] Remove the "it is not safe to remove an unused 'autorelease' message" ARC
migration error.

This is more trouble that it is worth; autoreleasing a value without holding on it
is a valid use-case, we should not "punish" correct code for the minority of
broken/fragile programs that depend on the behavior of  -autorelease.

Chris Lattner a3b0f52a72 enhance the intrinsic info stuff to emit encodings that don't fit in 32-bits into a
separate side table, using the handy SequenceToOffsetTable class.  This encodes all
these weird things into another 256 bytes, allowing all intrinsics to be encoded this way.

Filipe Cabecinhas b018345ddc We shouldn't save g_dummy_target_sp. Other code will simply call Destroy() on it.
TestBackticksWithoutATarget.BackticksWithNoTargetTestCase was calling
GetDummyTarget() when executing for x86_64. When performing session
tearDown, it would get destroyed (and everything would be invalid (arch,
etc).

Then the test would run for i386. The dummy target wasn't being
reinitialized and was invalid. lldb complained that 'current process state
is unsuitable for expression parsing'.
