[llvm-profdata][test] Change -Wl,-no-pie to -no-pie after D127808

The driver option -no-pie is preferred: Clang selects different crt*.o files,
though the PIC one usually can replace the non-PIC one.

[memprof] Store callsite metadata with memprof records.

To ease profile annotation, each of the callsites in a function can be
annotated with profile data - "IR metadata format for MemProf" [1]. This
patch extends the on-disk serialized record format to store the debug
information for allocation callsites incl inline frames. This change is
incompatible with the existing format i.e. indexed profiles must be
regenerated, raw profiles are unaffected.

This patch filters out callstack frames which can't be symbolized or if
the frames belong to the runtime. Symbolization may not be possible if
debug information is unavailable or if the addresses are from a shared
library. For now we only support optimization of the main binary which
is statically linked to the compiler runtime.
