Jakob Olesen c8708d9bf3 misc: Replace uses of __builtin_*_overflow() with <misc/math_extras.h>.
Use the new math_extras functions instead of calling builtins directly.

Change a few local variables to size_t after checking that all uses of
the variable actually expects a size_t.

Flavio Ceolin b45a287b02 toolchain: xcc: Builtin overflow functions return boolean
The builtin_*_overflow functions when available return a
boolean. Change internal definitions to return same type.

Anas Nashif d7fe69a6bc toolchain: xcc: __builtin_unreachable needs to be a loop
Functions are declared as noreturn but they do in fact return (when
control reaches the end of the body, since it doesn't enter an infinite
loop, it doesn't call other "noreturn" functions, etc.)

Daniel Leung 51e47180f0 toolchain: xcc: fake __builtin_umul[ll]_overflow
XCC doesn't provide these builtins so we have to define them
with minimal functionality for testing.

Rajavardhan Gundi 08172cdf83 xtensa: provide XCC compiler support for Xtensa
This patchset provides Xtensa's xcc compiler support for Xtensa
projects in Cmake. This requires the below environment variables
to be defined aptly. The appropriate xcc license information also
need to be supplied.

Andrew Boie 8b141dd83e xcc: fix __in_section_unique() and __COUNTER__
XCC assembler freaks out if a section name has __FILE__ in it,
forward slashes and quotation marks confuse it and result in
build errors.

This is not a perfect fix, its possible for two sections to collide,
but at worst this will result is some unnecessary space in noinit,
fooling gc-sections.

XCC also doesn't support __COUNTER__, use __LINE__ as a substitute.

Andrew Boie a2b324035c xtensa: move byte-order macros out of arch.h
These are macros that are expected to be defined at all times by
the compiler. We need them at the very beginning of kernel.h for
the k_thread definition, before it's possible to include arch.h.

Make a special toolchain header for XCC compiler and place these
defines in there. Otherwise inherit all the other GCC defines.
