Jakob Stoklund Olesen add79c6abf Run dead code elimination immediately after rematerialization. 
This may eliminate some uses of the spilled registers, and we don't want to
insert reloads for that.

Francois Pichet 3096d209bf Accept __declspec(dllimport) for function defined at class scope in Microsoft mode.

Chandler Carruth ffce245700 Fix a bug in how we were resolving the address of overloaded functions 
when the resolution took place due to a single template specialization
being named with an explicit template argument list. In this case, the
"resolution" doesn't take into account the target type at all, and
therefore can take place for functions, static member functions, and
*non-static* member functions. The latter weren't being properly checked
and their proper form enforced in this scenario. We now do so.

The result of this last form slipping through was some confusing logic
in IsStandardConversion handling of these resolved address-of
expressions which eventually exploded in an assert. Simplify this logic
a bit and add some more aggressive asserts to catch improperly formed
expressions getting into this routine.

Finally add systematic testing of member functions, both static and
non-static, in the various forms they can take. One of these is
essentially PR9563, and this commit fixes the crash in that PR. However,
the diagnostics for this are still pretty terrible. We at least are now
accepting the correct constructs and rejecting the invalid ones rather
than accepting invalid or crashing as before.

Bill Wendling fb63d55fe8 Rework the logic (and removing the bad check for an unreachable block) so that 
the FailBB dominator is correctly calculated. Believe it or not, there isn't a
functionality change here.

Cameron Zwarich ff811cc475 Do some simple copy propagation through integer loads and stores when promoting 
vector types. This helps a lot with inlined functions when using the ARM soft
float ABI. Fixes <rdar://problem/9184212>.

Bill Wendling 220c9f045b Don't try to add stack protector logic to a dead basic block. It messes up 
dominator information.

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.

Johnny Chen 6454e15f49 Add the ability to invoke lldb's disassemble command on the symbols digested from 
the 'image dump symtab' command.  The number of symbols to disassemble can be

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.

Johnny Chen 5e28aa5d9b Add an initial version of lldb-disasm.py script whose purpose is to iterate through 
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.
