Inomp_resolve_declare_variant, a code path generates a new decl for the 
base function – in doing so, it ignores the assembler name. As the 
included Fortran example shows, this will lead to a linker error. 
Solution: Also copy over the assembler name. Comments, suggestions, 
remarks before I commit it? Tobias PS: As a fallout of some testing, 
motivated by the original testcase, I have filled a couple of 
declare-variant and context-selector PRs: 113904 (dyn. 
user={condition(...)}), 113905 (multiple users of variant funcs), 113906 
(construct={...} lacks constructs).
