Add support for Intel Compiler

#1732 contains changes that make FDB compile with icc. However, due to what seems to be a compiler bug in icc, the resulting binary doesn't work (fdb crashes early).

Currently this is a low priority item, but eventually we might want to support that compiler to check whether we can use icc to get better performance.

FYI @kaomakino

Start by reviewing the changes in #1732 and reproducing the Intel Compiler build and early runtime crash described here. Done means FoundationDB both compiles with icc and produces a working binary; the issue does not identify specific files or tests.
