[Patch, testsuite] fix target/PR49614

[Iain Sandoe]

gcc.dg/vmx/gcc-bug-i.c is failing for powerpc*-*-*
with:
Excess errors: /opt/gcc/work/gcc/testsuite/gcc.dg/vmx/gcc-bug-i.c: 
16:22: warning: always_inline function might not be inlinable [- 
Wattributes]
this is because the function in question is declared:
static DO_INLINE int inline_me(vector signed short data) ;
where:
#define DO_INLINE __attribute__ ((always_inline))
so, unless  __attribute__ ((always_inline)) is intended to imply  
"inline",  the fix below is proposed,
OK for trunk?

gcc/testsuite:
	PR target/49614
