Uncovered by Uros Bizjak.
Before this patch the test would close the file descriptor but
not the os.File. When the os.File was GC'ed, the finalizer
would close the file descriptor again. That would cause
problems if the same file descriptor were returned by a later
call to open in another test.

when the def feeds another extend with a different mode. This works because
in merge_def_and_ext only calls combine_set_extension if the candidate for
removal has a wider mode than the def extend's mode, otherwise the def extend
mode is preserved. In combine_set_extension the def is modified to use the
wider candidate's mode.

This patch instruments many memory access patterns through builtins.
Basically, for a call like:
__builtin_memset (from, 0, n_bytes);
the patch would only instrument the accesses at the beginning and at
the end of the memory region [from, from + n_bytes]. This is the
strategy used by the llvm implementation of asan.
This instrumentation is done for all the memory access builtin
functions that expose a well specified memory region -- one that
explicitly states the number of bytes accessed in the region.
A special treatment is used for __builtin_strlen. The patch
instruments the access to the first byte of its argument, as well as
the access to the byte (of the argument) at the offset returned by
strlen.
For the __sync_* and __atomic* calls the patch instruments the access
to the bytes pointed to by the argument.
While doing this, I have added a new parameter to build_check_stmt to
decide whether to insert the instrumentation code before or after the
statement iterator. This allows us to do away with the
gsi_{next,prev} dance we were doing in the callers of this function.
Tested by running cc1 -fasan on variations of simple programs like:
int
foo ()
{
char foo[10] = {0};
foo[0] = 't';
foo[1] = 'e';
foo[2] = 's';
foo[3] = 't';
int l = __builtin_strlen (foo);
int n = sizeof (foo);
__builtin_memset (&foo[4], 0, n - 4);
__sync_fetch_and_add (&foo[11], 1);
return l;
}
and by starring at the gimple output which for this function is:
;; Function foo (foo, funcdef_no=0, decl_uid=1714, cgraph_uid=0)

value type stored in the hash table. The 'find' functions now may
take a different type from the value type. This requires introducing
a second typedef into the Descriptor conceptual type. Change the
Descriptor concept to use typedefs value_type and compare_type instead
of T. Change all users to match.
Add usage documentation to hash-table.h.
Tested on x86-64.
