Log:
Fix debuginfo-tests with GDB on Linux
Summary:
Split asan.c into asan.c and asan-blocks.c, which will be
darwin-specific. I suspect we could make it pass on Linux by adding
cmake to build BlocksRuntime from compiler-rt, but I'm not shaving that
yak yet.
asan.c and safestack.c: GDB and LLDB appear to print aggregates
differently today. Print individual elements instead of the entire
aggregate.
dbg-arg.c: GDB doesn't appear to print leading zeros when printing
pointers.
stack-var.c: Add the optnone attribute so that LLVM won't optimize away
this no-op function call. This should be a cross-platform failure
observable on Mac, so this is surprising.
