mono/utils/mono-compiler.h has incorrect trunc() definition for Visual
Studio, causing overflow exceptions to be thrown from int->float conversions
with negative inputs.

Line 88 is:
  #define trunc(x)    floor((x))
when it should be something like:
  #define trunc(x)    (((x) < 0) ? ceil((x)) : floor((x)))
