The  age  of   the  intel  compiler  support  is  so   old  as  to  be
uninteresting. No recent recports of  intel compiler support have been
received.  Remove  all the  special  case  workarounds for  the  Intel
compiler. Should there be interest in supporting the compiler, contact
me and I'll work with people to make it happen, though I suspect these
instances are more likely to be in the way than to be helpful.

From: Alex Richardson <arichardson@FreeBSD.org>

This makes roundup2/rounddown2 type- and const-preserving and allows
using it on pointer types without casting to uintptr_t first. Not
performing pointer-to-integer conversions also helps the compiler's
optimization passes and can therefore result in better code generation.
When using it with integer values there should be no change other than
the compiler checking that the alignment value is a valid power-of-two.

I originally implemented these builtins for CHERI a few years ago and
they have been very useful for CheriBSD. However, they are also useful
for non-CHERI code so I was able to upstream them for Clang 10.0.

Rationale from the clang documentation:
Clang provides builtins to support checking and adjusting alignment
of pointers and integers. These builtins can be used to avoid relying
on implementation-defined behavior of arithmetic on integers derived
from pointers. Additionally, these builtins retain type information
and, unlike bitwise arithmetic, they can perform semantic checking on
the alignment value.

There is also a feature request for GCC, so GCC may also support it in
the future: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98641

What about the Intel compiler support in newlib?  Not that I have seen any
evidence that somebody is actually using one...

Other than that, the patchset looks good to me.

The Intel compiler support was added through a <sys/cdefs.h> 
synchronization with FreeBSD in 2013 and 2015. The Intel compiler was 
probably never used together with Newlib.
