Mehdi Amini 793a2b15e7 Make the default triple optional by allowing an empty string
When building LLVM as a (potentially dynamic) library that can be linked against
by multiple compilers, the default triple is not really meaningful.
We allow to explicitely set it to an empty string when configuring LLVM.
In this case, said "target independent" tests in the test suite that are using
the default triple are disabled by matching the newly available feature
"default_triple".

; Check that we emit ranges for this CU since we have a function with and
; without debug info.
; Note: This depends upon the order of output in the .o file. Currently it's
; in order of the output to make sure that the CU has multiple ranges since
; there's a function in the middle. If they were together then it would have
; a single range and no DW_AT_ranges.
