Benjamin Kramer 09a51bab5d Add an argument to APInt's magic udiv calculation to specify the number of bits that are known zero in the divided number. 
This will come in handy soon.

Jakob Stoklund Olesen 8630840c30 Dead code elimination may separate the live interval into multiple connected components. 
I have convinced myself that it can only happen when a phi value dies. When it
happens, allocate new virtual registers for the components.

Richard Smith 9647d3ca02 Fix PR9488: 'auto' type substitution can fail (for instance, if it creates a reference-to-void type). Don't crash if it does. 
Also fix an issue where type source information for the resulting type was being lost.

Ted Kremenek 2551fbe928 Don't construct two CFGs just to run -Wuninitialized. While this causes new warnings to be flagged under -Wconditional-uninitialized, this is something we 
can improve over time.

Ted Kremenek 3e5ad5932e Tweak RegionStore's handling of lazy compound values to use the 'Default' versus 'Direct' binding key, thus allowing specific elements of an array/struct to be overwritten without

Johnny Chen 6f6fb3e515 Add a Python script to take an executable, run gdb to disassemble a function, 
read the memory contents of the function, and then feed the bytes to the
'llvm-mc -disassemble' command.

It uses the pexpect module located under ToT/test/pexpect-2.4 directory to
automate the interaction with gdb.  This is used initially to test the low
level ARM disassembler of llvm.

Douglas Gregor c2b97994ea When libclang visits a translation unit via clang_visitChildren(), 
walk the preprocessing record *before* walking the declarations, so
they we pretend that we actually respect the phases of translation.

We still walk the preprocessing record after the declarations when
performing token annotation or finding the cursor at a location, since
those routines depend on those semantics.

Fixes <rdar://problem/9137195>.

The register allocator needs to adjust its live interval unions when that happens.

Jakob Stoklund Olesen e29d63e98a Tag cached interference with a user-provided tag instead of the virtual register number. 
The live range of a virtual register may change which invalidates the cached
interference information.

Cameron Zwarich ac106273d4 The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byte 
rather than an int. Thankfully, this only causes LLVM to miss optimizations, not
generate incorrect code.

This just fixes the zext at the return. We still insert an i32 ZextAssert when
reading a function's arguments, but it is followed by a truncate and another i8
ZextAssert so it is not optimized.
