Jakob Stoklund Olesen d8af5298d1 Properly enable rematerialization when spilling after live range splitting. 
The instruction to be rematerialized may not be the one defining the register
that is being spilled. The traceSiblingValue() function sees through sibling
copies to find the remat candidate.

Evan Cheng e2086e740f Optimizing (zext A + zext B) * C, to (VMULL A, C) + (VMULL B, C) during 
isel lowering to fold the zero-extend's and take advantage of no-stall
back to back vmul + vmla:
 vmull q0, d4, d6
 vmlal q0, d5, d6
is faster than
 vaddl q0, d4, d5
 vmovl q1, d6                                                                                                                                                                             
 vmul  q0, q0, q1

This allows us to vmull + vmlal for:
    f = vmull_u8(   vget_high_u8(s), c);
    f = vmlal_u8(f, vget_low_u8(s),  c);

Ted Kremenek 03325c4be9 Add workaround for Sema issue found in <rdar://problem/9188004>, which leads to an assertion failure in the uninitialized variables analysis. The problem is that Sema isn't properly registering a variable in a DeclContext (which -Wuninitialized relies on), but 
my expertise on the template instantiation logic isn't good enough to fix this problem for real.  This patch worksaround the
problem in -Wuninitialized, but we should fix it for real later.

Bill Wendling 96f962fdff In some cases, the "fail BB dominator" may be null after the BB was split (and 
becomes reachable when before it wasn't). Check to make sure that it's not null
before trying to use it.

all the symbols for an executable image and to issue the lldb 'disassemble' command
on each symbol.  The initial version just dumps the symbol table.

Kevin Enderby f3070dc40d Again adding a C API to the disassembler for use by such tools as Darwin's 
otool(1), this time with the needed fix for case sensitive file systems :) .
This is a work in progress as the interface for producing symbolic operands is
not done.  But a hacked prototype using information from the object file's
relocation entiries and replacing immediate operands with MCExpr's has been
shown to work with no changes to the instrucion printer.  These APIs will be
moved into a dynamic library at some point.

Jakob Stoklund Olesen 28d79cdeab Drop interference reassignment in favor of eviction. 
The reassignment phase was able to move interference with a higher spill weight,
but it didn't happen very often and it was fairly expensive.

The existing interference eviction picks up the slack.

Chandler Carruth edcc04e05b Add tests for the uninitialized checks added in r128376. Also clean up 
and flesh out the existing uninitialized testing for field initializers.

The tests come from Richard's original patch, but I've cleaned them up
a bit and ordered them more naturally.

Also, I added a test for the most simple base case:
int x = x;

And it turns out we miss this one! =[ That and another bad FIXME on the
field initializer checking are left in the test.

Chandler Carruth 24284afa2d Flip the default for showing include stacks on notes to false. This 
required modifying a few tests that specifically use note include stacks
to check the source manager's view of include stacks. I've simply added
the flag to these tests for now, they may have to be more substantially
changed if we decide to remove support for note include stacks
altogether.

Also, add a test for include stacks on notes that was supposed to go in
with the previous commit.
