5b66b31774 MOVi16 should also be marked as a UnaryDP instruction, i.e., it doesn't have a 
Rn operand.

b33dbc5019 Change TAILJMP's to be varargs and transfer implicit uses over from TCRETURN's. Otherwise the missing uses can make post-regalloc scheduling do bad things. This fixes 403.gcc.

25df248382 Fix a gross typo: ARMv6+ may or may not support unaligned memory operations. 
Even if they are suported by the core, they can be disabled
(this is just a configuration bit inside some register).

Allow unaligned memops on darwin and conservatively disallow them otherwise.

76e5d70c57 MC/X86 AsmParser: Handle absolute memory operands correctly. We were doing 
something totally broken and parsing them as immediates, but the .td file also
had the wrong match class so things sortof worked. Except, that is, that we
would parse
  movl $0, %eax
as
  movl 0, %eax
Feel free to guess how well that worked.

34a6afc68d Modified encoding bits specification for VFP instructions. In particular, the D 
bit (Inst{22}) and the M bit (Inst{5}) should be left unspecified.  For binary
format instructions, Inst{6} and Inst{4} need to specified for proper decodings.

091217be6f Kill ModuleProvider and ghost linkage by inverting the relationship between 
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.

Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
other languages still use the ModuleProvider concept.  It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

85476f304c Perform trivial tail call optimization for callees with "C" ABI. These are done 
even when -tailcallopt is not specified and it does not require changing ABI.
First case is the most trivial one. Perform tail call optimization when both
the caller and callee do not return values and when the callee does not take
any input arguments.

67a69dd2ed Eliminate target hook IsEligibleForTailCallOptimization. 
Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.
