0fdb05deb9 Call release() directly when cleaning up the remaining DomainValues. 
There is no need to involve the LiveRegs array and kill() any longer.

35e932483a Handle reference counts in one function: release(). 
This new function will decrement the reference count, and collapse a
domain value when the last reference is gone.

This simplifies DomainValue reference counting, and decouples it from
the LiveRegs array.

9cae2d2225 Add a hack to the scheduler to disable pseudo-two-address dependencies in 
basic blocks containing calls. This works around a problem in which
these artificial dependencies can get tied up in calling seqeunce
scheduling in a way that makes the graph unschedulable with the current
approach of using artificial physical register dependencies for calling
sequences. This fixes PR11314.

e1b3e11c15 Clear old DomainValue after merging. 
The old value may still be referenced by some live-out list, and we
don't wan't to collapse those instructions twice.

This fixes the "Can only swizzle VMOVD" assertion in some armv7 SPEC
builds.

5207bf2177 Lower mem-ops to unaligned i32/i16 load/stores on ARM where supported. 
Add support for trimming constants to GetDemandedBits. This fixes some funky
constant generation that occurs when stores are expanded for targets that don't
support unaligned stores natively.

d752e0f7e6 Added invariant field to the DAG.getLoad method and changed all calls. 
When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses

ad6eef4a65 This patch handles unaligned loads and stores in Mips JIT. Mips backend 
implements unaligned loads and stores with assembler macro-instructions
ulw, usw, ulh, ulhu, ush, and this patch emits corresponding instructions
instead of these macros. Since each unaligned load/store is expanded
into two corresponding loads/stores where offset for second load/store is
modified by +3 (for words) or +1 (for halfwords).

Patch by Petar Jovanovic and Sasa Stankovic.

b26c7727c9 Kill and collapse outstanding DomainValues. 
DomainValues that are only used by "don't care" instructions are now
collapsed to the first possible execution domain after all basic blocks
have been processed.  This typically means the PS domain on x86.

For example, the vsel_i64 and vsel_double functions in sse2-blend.ll are
completely collapsed to the PS domain instead of containing a mix of
execution domains created by isel.
