Hamming Weight or "popcount" consists in counting the number of bits set
to 1 in a particular word. This commit adds a macro to be able to use
the existing builtin for this purpose with the GCC compiler.

Removing _ prefix from ALIAS_OF() macro in order to indicate
that it is for public use.
The macro can be used whenever the FUNC_ALIAS() cannot. The
FUNC_ALIAS() macro can give errors if the aliased function
has parameters like uint16_t etc.

The toolchain headers included an abstraction for defining symbol
names in assembly context in the situation where we're using a
DOS-style assembler that automatically prepends an underscore to
symbol names.
We aren't. Zephyr is an ELF platform. None of our toolchains do
this. Nothing sets the "TOOL_PREPENDS_UNDERSCORE" macro from within
the project, and it surely isn't an industry standard. Yank it out.
Now we can write assembler labels in natural syntax, and a few other
things fall out to simplify too.
(NOTE: these headers contain assembly code and will fail checkpatch.
That is an expected false positive.)

This doesn't make any assumptions on calling conventions or
the structure of the stack, and should thus be portable to
compilers that implement different C calling conventions.
In order for the rewritten functions to take up the same code
size as the pure-asm counterparts, -fomit-frame-pointer has
been specified for each of them, otherwise an extra 4 bytes
is used for every function.
The generated assembly code by these new functions has been
verified in GDB to be the same as the old ones, except a few
trivial things like particular registers used.

Routines are no longer flagged as constructors using the FUNC_CONSTRUCT(level)
macro. This is because some compilers do not support constructor levels.
To indicate that a routine should be a constructor, the SYS_PREKERNEL_INIT()
macro should be used AFTER the definition of the routine. For example ...
void my_library_init(void)
{
...
}
SYS_PREKERNEL_INIT(my_library_init, 500);
The first parameter to SYS_PREKERNEL_INIT() is the name of the routine. The
second is the priority level (000...999). The lower the number, the higher
the priority. NOTE: It is important that all three digits are specified;
otherwise the linker may put the constructors in an undesired order.
