Respect include_inlines when looking up functions in SymbolFileDWARF 

Summary:
SymbolFileDWARF was not respecting the include_inlines argument in function lookup in all code
paths. This resulted in an attempt to call an inlined function during expression evaluation,
which is impossible, and usually resulted in a segfault in the inferior. This patch makes sure
include_inlines is respected in all code paths.
