[PING][PATCH] Fix PR gdb/17720 (Function names appear without namespace/class prefixes in backtrace for optimized code)

[Martin Galvan <martin.galvan@tallertechnologies.com>]

This bug was being caused by die_needs_namespace returning 0 for a DIE whose tag was DW_TAG_inlined_subroutine. This meant that dwarf2_physname would simply return the DIE's name attribute (which in our case would be "method"). Therefore, when new_symbol_full called SYMBOL_SET_NAMES, the linkagename argument wasn't the demangled name as it should have.

This patch adds a case which would return 1 for DW_TAG_inlined_subroutine in die_needs_namespace. It's tested both for classes and namespaces.

I have a company-wide copyright assignment. I don't have commit access, though, so it would be great if anyone could commit this for me.

	* dwarf2read.c (die_needs_namespace): Return 1 for
	DW_TAG_inlined_subroutine.
