Currently InferAnalyze always adds bucket to the message. Later, python code
strips it, but not everywhere. Changes:
1. Since it's easy to not write bucket in ocaml, stop writing them by default.
2. Add option to print them to InferAnalyze and pass it if infer is in debug mode.
Test Plan:
1. Run on openssl, confirm that no bucket info is written to stdout and csv
2. Run on small example in debug mode and see buckets on stdout

Using InferBuiltins.assume previously caused an assertion failure in the analyzer. Fixed this, and fixed the implementation of the assume builtin to block when the assumed condition cannot hold.
Test Plan: Added several new tests.

This adds basic support for function attributes in Sil, and for translating
attributes from the clang frontend to these new Sil attributes. For now only
the sentinel attribute is translated.
Note that attributes normally have parameters, but they are currently missing
from the clang plugin.
Test Plan:
Add
(match Sil.get_sentinel_func_attribute_value (Cfg.Procdesc.get_attributes callee_pdesc).Sil.func_attributes with
| Some _ -> L.out "found sentinel attribute!\n"
| _ -> ());
between lines 947 and 948 of symbExec.ml, then analyze a file containing:
int add_all_ints(int a, ...) __attribute__ ((sentinel));
int foo(void) { return add_all_ints(1, 2, 3, (void *)0); }
then `grep 'found sentinel' infer-out/log/analyzer_out`
-> the sentinel attribute is correctly passed from the frontend to the backend.

This changes "Starting analysis" into
"Starting analysis (Infer version XXX)".
Test Plan:
infer -- clang -c hello.c
shows "Starting analysis (Infer version git-6b9fb8838bcabd2af881554d296963a849b14f50)"
