Initial support for the ICL compiler on windows. Requires a new c99wrap
with ICL support (1.0.2+).
Currently not much different speed wise compared to msvc. In the future
with a few changes it can be made to support the inline asm. This would
be the primary reason for using it.
Passed all fate tests, versions tested:
13.1.1.171 (2013 Update 3) x86 and x64
12.1.5.344 (2011 Update 11) x86 and x64
