Changes since v1:
- Updated the error message to mention that arm_mve_types.h needs to be
included.
- Corrected some spelling errors in commit message.
As the warning for pure functions returning void is not related to this
patch, I'll leave it for you Christophe to look into. :)
Ok for trunk and releases/gcc-14?

Starting with r14-435-g00d97bf3b5a, doing `#pragma arm "arm_mve.h"
false` or `#pragma arm "arm_mve.h" true` without first doing
`#pragma arm "arm_mve_types.h"` causes GCC to ICE.
gcc/ChangeLog:
PR target/117408
* config/arm/arm-mve-builtins.cc(handle_arm_mve_h): Detect if MVE
types are missing and if so, return error.
gcc/testsuite/ChangeLog:
PR target/117408
* gcc.target/arm/mve/pr117408-1.c: New test.
* gcc.target/arm/mve/pr117408-2.c: Likewise.
