  Hi All,

This patch fixes the implementation of the existing __arm_vld1q_z* and
__arm_vst1q_p* MVE intrinsic functions.

The MVE ACLE allows for __ARM_MVE_PRESERVE_USER_NAMESPACE to be defined,
which removes definitions for intrinsic functions without the __arm_
prefix. __arm_vld1q_z* and __arm_vst1q_p* are currently implemented via
calls to vldr* and vstr*, which results in several compile-time errors when
__ARM_MVE_PRESERVE_USER_NAMESPACE is defined. This patch replaces these
with calls to their prefixed counterparts, __arm_vldr* and __arm_str*,
and adds a test covering the definition of __ARM_MVE_PRESERVE_USER_NAMESPACE.

Regression tested on arm-eabi -- no issues.

Thanks,
Murray

gcc/ChangeLog:

        * config/arm/arm_mve.h (__arm_vst1q_p_u8): Use prefixed intrinsic
        function.
        (__arm_vst1q_p_s8): Likewise.
        (__arm_vld1q_z_u8): Likewise.
        (__arm_vld1q_z_s8): Likewise.

Is there a PR in bugzilla for this?

No, not at this time. It's something I came across whilst
making changes of my own.

For completeness, the ACLE specification I am referencing
has been added below [1].

Thanks,
Murray

Andre created one today and I've now pulled this patch in.  Thanks, and 
sorry for the delay getting it committed.
