[Xtensa] preserve assembly no-transform flag for data

[Xtensa] preserve assembly no-transform flag for data

[Bob Wilson]

[-- Attachment #1: Type: text/plain, Size: 535 bytes --]

This patch fixes an obscure case where the Xtensa "no-transform" directive was 
not being honored by the linker for data included inside the no-tranform region. 
  The property table flags used to mark such a region were only being set for 
instructions and literals.  Committed.

	* config/tc-xtensa.c (xtensa_elf_cons): Set frag flags for
	expressions without suffixes.
	(get_frag_property_flags): Preserve is_no_transform flag for frags
	not marked as either instructions or literals.
