Fixes to __load and __store.
Added __add, __mul, __equal, __not_equal, __extract_elements, __smear_i64, __cast_sext, __cast_zext,
and __scatter_base_offsets32_float.
__rcp_varying_float now has a fast-math and full-precision implementation.

Some modules require an include of unistd.h (e.g. for getcwd and isatty
definitions).
These changes were required to build successfully on a Fedora 17 system,
using GCC 4.7.0 & glibc-headers 2.15.
If --opt=fast-math is used then the generated code contains:
#define ISPC_FAST_MATH 1
Otherwise it contains:
#undef ISPC_FAST_MATH
This allows the generic headers to support the user's request.

This should help with performance of the generated code.
Updated the relevant header files (sse4.h, generic-16.h, generic-32.h, generic-64.h)
Updated generic-32.h and generic-64.h to the new memory API

(Rather than implicitly with a using declaration.) This will
allow for some further changes to ISPC's C backend, without collision
with ISPC's namespace. This change aims to have no effect on the code
generated by the compiler, it should be a big no-op; except for its
side-effects on maintainability.

We need to do this since it's illegal to have nested foreach statements, but
nested foreach_unique, or foreach_unique inside foreach, etc., are all fine.
It's now legal to write:
struct Foo { Foo *next; };
previously, a predeclaration "struct Foo;" was required. This fixes
issue #287.
This change also fixes a bug where multiple forward declarations
"struct Foo; struct Foo;" would incorrectly issue an error on the
second one.
The string to be printed is accumulated into a local buffer before being sent to
puts(). This ensure that if multiple threads are running and printing at the
same time, their output won't be interleaved (across individual print statements--
it still may be interleaved across different print statements, just like in C).
Issue #293.
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.
We now use InternalLinkage for the 'programIndex' symbol (and similar)
if we're not compiling with debugging symbols. This prevents those
symbol names/definitions from polluting the global namespace for
the common case.
Basically addresses Issue #274.
