Earlier, function-starts.test failed when directory path contained '_main', because objdump prints out the entire directory path, and there is an implicit-check-not for '_main'. There's three ways in which [function starts are printed by llvm-objdump](https://llvm.org/docs/CommandGuide/llvm-objdump.html#cmdoption-llvm-objdump-function-starts): With the "addr" mode, there will be no "_main"\ With "names", it'll be printed as "_main\n"\ With "both", it'll be printed as "<addr> _main\n". The existing check for function-starts=addrs checks that the pattern for "names" or "both" does not get printed. This MR changes the RUN lines to take stdin input, so that no directory path is printed, and stray _main strings in the directory path will not make the test fail.

## This test verifies that llvm-objdump correctly prints function starts data.

|
## Note: we read input from stdin instead of from a file, because llvm-objdump prints
|
|
## the filename in its output. If the filename contains the string "_main", then the
|
|
## check will incorrectly get triggered.
