ccdbddd388 Add peephole optimization to match int8/int16 averages. 
Match the following patterns in IR, turning them into target-specific
intrinsics (e.g. PAVGB on x86) when possible.

(unsigned int8)(((unsigned int16)a + (unsigned int16)b + 1)/2)
(unsigned int8)(((unsigned int16)a + (unsigned int16)b)/2)
(unsigned int16)(((unsigned int32)a + (unsigned int32)b + 1)/2)
(unsigned int16)(((unsigned int32)a + (unsigned int32)b)/2)
(int8)(((int16)a + (int16)b + 1)/2)
(int8)(((int16)a + (int16)b)/2)
(int16)(((int32)a + (int32)b + 1)/2)
(int16)(((int32)a + (int32)b)/2)

5b20b06bd9 Add avg_{up,down}_int{8,16} routines to stdlib 
These compute the average of two given values, rounding up and down,
respectively, if the result isn't exact.  When possible, these are
mapped to target-specific intrinsics (PADD[BW] on IA and VH[R]ADD[US]
on NEON.)

A subsequent commit will add pattern-matching to generate calls to
these intrinsincs when the corresponding patterns are detected in the
IR.)

bba84f247c Improved optimization of vector select instructions. 
Various LLVM optimization passes are turning code like:

%cmp = icmp lt <8 x i32> %foo, %bar
%cmp32 = sext <8 x i1> %cmp to <8 x i32>
. . .
%cmp1 = trunc <8 x i32> %cmp32 to <8 x i1>
%result = select <8 x i1> %cmp1, . . .

Into:

%cmp = icmp lt <8 x i32> %foo, %bar
%cmp32 = zext <8 x i1> %cmp to <8 x i32>   # note: zext
. . .
%cmp1 = icmp ne <8 x i32> %cmp32, zeroinitializer
%result = select <8 x i1> %cmp1, …

Which in turn isn't matched well by the LLVM code generators, which
in turn leads to fairly inefficient code.  (i.e. it doesn't just emit
a vector compare and blend instruction.)

Also, renamed VSelMovmskOptPass to InstructionSimplifyPass to better
describe its functionality.

53414f12e6 Add SSE4 target optimized for computation with 8-bit datatypes. 
This change adds a new 'sse4-8' target, where programCount is 16 and
the mask element size is 8-bits.  (i.e. the most appropriate sizing of
the mask for SIMD computation with 8-bit datatypes.)
