ee7de1cff0 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.

224434deec 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

0c9933e29f 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.

4b12a5b7fc Enable support for returning i1, i8, and i16. Nothing special todo as it's the 
callee's responsibility to sign or zero-extend the return value.  The additional
test case just checks to make sure the calls are selected (i.e., -fast-isel-abort
doesn't assert).

9380d5daff 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.

c1846a4d5e Use a reverse post order instead of a DFS order. 
The enterBasicBlock() function is combining live-out values from
predecessor blocks.  The RPO traversal means that more predecessors
have been visited when that happens, only back-edges are missing.

b53be3a67d Expand V_SET0 to xorps by default. 
The xorps instruction is smaller than pxor, so prefer that encoding.

The ExecutionDepsFix pass will switch the encoding to pxor and xorpd
when appropriate.
