* Simplify x86 arch check

* Fix sleef compilation when CMAKE_OSX_ARCHITECTURES is passed

Test plan:
  Run `cmake .. -DCMAKE_OSX_ARCHITECTURES=x86_64 -G Ninja; ninja` on M1 Mac
  Run `cmake .. -DCMAKE_OSX_ARCHITECTURES=arm64 -G Ninja; ninja` on x86 Mac

* Compile host executable as universable binaries on OS X
If multiarch option is passed

With this patch, double2 and float2 data types can be used instead of Sleef_double2 and Sleef_float2 for CUDA.
It also eliminates a need for including float.h when using the CUDA header file.

C standard does not define how sign bit should be handled during left shift, which triggers UBSAN runtime error:
```
src/libm/sleefsimdsp.c:3031:101: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
```
Discovered while working on https://github.com/pytorch/pytorch/pull/48275

C standard do not define have left shift should affect the sign bit, which results in the following runtime error if `vilogbk_vi_vd` is compiled by clang with sanitizer checks enabled:
```
sleef/src/libm/sleefsimddp.c:329:49: runtime error: left shift of 4095 by 20 places cannot be represented in type 'int'
```
Can be fixed by explicitly specifying type of shift 1st operand as unsigned: i.e. replacing `1` with `1U`

CMAKE_SYSTEM_PROCESSOR is set to "arm64" on Apple M1 machines

This patch adds z15 VX support, following issue https://github.com/shibatch/sleef/issues/317

.
It also changes the suffix zvector2 to vxe and vxe2.
In order to enable z15 VXE2 support, it requires clang-10.
However, it seems that clang-9 and later have a bug in handling orderedness of comparison.
Thus, it passes the tests only if optimizations are turned off.
