Clang normally disguises as GCC (defining __GNUC__), and thus get
all the normal GCC specific attributes.
Clang can also work as a drop-in replacement for MSVC, and in these
cases, it doesn't define __GNUC__, but defines _MSC_VER instead.
Even in these setups, it still supports the GCC style attributes,
thus use them, especially where there isn't any MSVC specific
version, or where the MSVC specific version doesn't work on clang
(for DECLARE_ASM_CONST).

Prior to this on msvc/icl there was no handling of deprecated functions
and the deprecated warning was disabled.
After enabling there are a number of warnings relating to the CRT and
the use of the non-secure versions of several functions. Defining
_CRT_SECURE_NO_WARNINGS silences these warnings.

With unknown attribute warnings disabled, these checks are no
longer needed. Removing them improves readability while having
no effect on generated code.

also attributes.h is public and external api and can thus not depend
on configure tested compiler support thus this part is removed. A
different solution must be found if this breaks for some compiler
which i hope it does not.
