Rafael Espindola 5054362920 Always create a temporary symbol to use with the cfi frame. 
This is a small simplification and a small step in fixing pr18743 since
private functions on MachO should be using a 'l' prefix.

Iain Sandoe 618def651b [patch] Adjust behavior of FDE cross-section relocs for targets that don't support abs-differences. 
Modern versions of OSX/Darwin's ld (ld64 > 97.17) have an optimisation present that allows the back end to omit relocations (and replace them with an absolute difference) for FDE some text section refs.

This patch allows a backend to opt-in to this behaviour by setting "DwarfFDESymbolsUseAbsDiff".  At present, this is only enabled for modern x86 OSX ports.

Rafael Espindola c48e10cd54 Assume .cfi_startproc is the first thing in a function. If the function is 
externally visable, create a local symbol to use in the CFE. If not, use the
function label itself.

Fixes PR10420.
