Honor collapse_debuginfo when dealing with MIR-inlined functions inside macros.

Browse Source 
The test relies on the fact that inlining more than 2^12 calls at the same
callsite will trigger a panic (and after the following commit, a warning) due to
LLVM limitations but with collapse_debuginfo the callsites should not be the
same.
