Alex Richardson	fb9942f876	[AsmParser] Add source location to all errors related to .cfi directives ... I was trying to add .cfi_ annotations to assembly code in the FreeBSD kernel and changed a macro that then resulted in incorrectly nested directives. However, clang's diagnostics said the error was happening at <unknown>:0. This addresses one of the TODOs added in D51695.

Kristina Brooks	1a41a116ec	[MC][DWARF][AsmParser] Ensure nested CFI frames are diagnosed. ... This avoids a crash (with asserts) or bad codegen (without asserts) in Dwarf streamer later on. This patch fixes this condition in MCStreamer and propogates SMLoc down when it's available with an added bonus of source locations for those specific types of errors. Further patches could use similar improvements as currently most non-Windows CFI directives lack an SMLoc parameter. Modified an existing test to verify source location propogation and added an object-file version of it to verify that it does not crash in addition to a standalone test to only ensure it does not crash.
