Subject: fix the definitions of ConstTextCoalSection/ConstDataCoalSection to
 keep "Text" in sync with the "pure instructions" section attribute. Lack of
 this attribute was preventing the assembler from emitting multibyte noops
 instructions for templates (and inlines, and other coalesced stuff) and was
 causing the assembler to mismatch .o files.

This fixes rdar://8018335
