0c5742b6f8 Implement new naming scheme for --target. 
Now targets are named like "<isa>-i<mask size>x<gang size>", e.g.
"sse4-i8x16", or "avx2-i32x16".

The old target names are still supported.

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.)

d9c38b5c1f Remove support for using SVML for math lib routines. 
This path was poorly maintained and wasn't actually available on most
targets.

b6df447b55 Add reduce_add() for int8 and int16 types.

63ed90b0fd docs/build.sh runs rst2html rather than rst2html.py 
Explicitly documented that fact that ICC needs the -mmic flag to compile for KNC.
Updated ISPC User Guide with details on ICC compiler options that impact FP performance in generated code.

2c640f7e52 Add support for RDRAND in IvyBridge. 
The standard library now provides a variety of rdrand() functions
that call out to RDRAND, when available.

54459255d4 Add unmasked { } statement. 
This reestablishes an "all on" execution mask for the gang, which can
be useful for nested parallelism..

46716aada3 Switch to unordered floating point compares. 
In particular, this gives us desired behavior for NaNs (all compares
involving a NaN evaluate to true).  This in turn allows writing the
canonical isnan() function as "v != v".

Added isnan() to the standard library as well.

8fd9b84a80 Update seed_rng() in stdlib to take a varying seed. 
Previously, we were trying to take a uniform seed and then shuffle that
around to initialize the state for each of the program instances.  This
was becoming increasingly untenable and brittle.

Now a varying seed is expected and used.

2aa61007c6 Remove memory_barrier() calls from atomics. 
This was unnecessary overhead to impose on all callers; the user
should handle these as needed on their own.

Also added some explanatory text to the documentation that highlights
that memory_barrier() is only needed across HW threads/cores, not
across program instances in a gang.

55b81e35a7 Modify rules for default variability of pointed-to types. 
Now, the pointed-to type is always uniform by default (if an explicit
rate qualifier isn't provided).  This rule is easier to remember and
seems to work well in more cases than the previous rule from 6d7ff7eba2.
