[PATCH] Fix ICE in arm_function_in_section_p (PR target/38695)

[Jakub Jelinek]

Hi!

pr37433.c testcase fails on ARM, because SYMBOL_REF_DECL of the called
symbol isn't necessarily FUNCTION_DECL, in the testcase it is STRING_CST,
could be VAR_DECL etc.  DECL_SECTION_NAME isn't defined for STRING_CST,
nor other macros.  Fixed by only trying sibcall if decl is a FUNCTION_DECL.
Other ports also check tree code before using DECL_SECTIO_NAME etc.

Laurent regtested this on arm, see
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38695#c6
Ok for trunk?
