6181ce59ae FunctionCallExpr bug: launch count wasn't being type checked, optimized. 
This manifested itself by a call to an overloaded function in a launch count 
expression that wasn't being resolved.

afcd42028f Add support for function pointers. 
Both uniform and varying function pointers are supported; when a function
is called through a varying function pointer, each unique function pointer
value across the running program instances is called once for the set of
active program instances that want to call it.

39ed7e14b2 Various improvements to function overload resolution. 
Generalize the overload resolution code to be based on estimating a
  cost for various overload options and picking the one with the
  minimal cost.
Add a step that considers type conversions that are guaranteed to
  not lose information in function overload resolution.
Print better diagnostics when we can't find an unambiguous match.

sse4-x2 target.

3cb0115dce Add routines to standard library to do efficient AOS/SOA conversions. 
Currently, we just support 3 and 4-wide variants (i.e. xyzxyz.. and xyzwxyzw..),
for int32 and float types.

cb7976bbf6 Added updated task launch implementation that now tracks task groups. 
Within each function that launches tasks, we now can easily track which
tasks that function launched, so that the sync at the end of the function
can just sync on the tasks launched by that function (not all tasks
launched by all functions.)

Implementing this led to a rework of the task system API that ispc generates
code to call; the example task systems in examples/tasksys.cpp have been
updated to conform to this API.  (The updated API is also documented in
the ispc user's guide.)

As part of this, "launch[n]" syntax was added to launch a number of tasks
in a single launch statement, rather than requiring a loop over 'n' to
launch n tasks.

This commit thus fixes issue #84 (enhancement to launch multiple tasks from
a single launch statement) as well as issue #105 (recursive task launches
were broken).
