d: Recognize pragma(inline) in the code generator.
Pragma inline affects whether functions are inlined or not. If at the
declaration level, it affects the functions declared in the block it
controls. If inside a function, it affects the function it is enclosed
by. Support has been in the front-end for some time, but the
information was not leveraged by the code generation pass.
gcc/d/ChangeLog:
* decl.cc (get_symbol_decl): Set DECL_DECLARED_INLINE_P or
DECL_UNINLINABLE for declarations with pragma(inline).
* toir.cc (IRVisitor::visit (GccAsmStatement *)): Set ASM_INLINE_P if
in function decorated with pragma(inline).
