It is OK to include <adxintrin.h> for IA MCU since GCC can generate ADX
intrinsics with alternative instuctions if ADX isn't enabled.

	PR target/66746
	* config/i386/x86intrin.h: Include <adxintrin.h> even if
	__iamcu__ is defined.

On x86, the "long double" type is platforma specific, which may be the
same as double or __float128.  Since pr37870.c requires 80-bit floating
point type, it should be compiled with -mlong-double-80.

	* gcc.target/i386/pr37870.c (dg-options): Add -mlong-double-80.
