Fixes for intrinsics unsupported in earlier LLVM versions.
...
Specifically, don't use the half/float conversion routines with
LLVM 3.0, and don't try to use RDRAND with anything before LLVM 3.2.

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

Add separate variants of memory built-ins for floats and doubles.
...
Previously, we'd bitcast e.g. a vector of floats to a vector of i32s and then
use the i32 variant of masked_load/masked_store/gather/scatter. Now, we have
separate float/double variants of each of those.

Gather/scatter function improvements in builtins.
...
More naming consistency: _i32 rather than i32, now.
Also improved the m4 macros to generate these sequences to not require as
many parameters.

Add separate set of builtins for AVX2.
...
(i.e., stop just reusing the ones for AVX1).
For now the only difference is that the int/uint min/max
functions call the new intrinsic for that. Once gather is
available from LLVM, that will go here as well.
