Fix some problems in SpeculativelyExecuteBB.  Basically,
because of dead code, a phi could use the speculated instruction
that was not in "BB2".  Make this check explicit and tighten up
some other corners.  This fixes PR3292.  No testcase becauase this
depends entirely on visitation order of blocks and requires a
sequence of 8 passes to repro.

Fix copy and pasted typos that prevented strtok_r, realloc, getenv, ungetc,
putc, puts, perror, vscanf and vsscanf from getting annotations.

Add annotations for eight printf functions, memalign, pread and pwrite.

On Linux, llvm-gcc sometimes renames strdup, getc, putc, strtok_r, scanf and
sscanf. Match the alternate function names.

Fix a crash annotating opendir.

Don't mark fsetpos's second parameter as nocapture. It's supposed to be
captured.

Do mark fopen's path and mode strings as nocapture. Mark ferror as readonly,
but not fileno which may set errno.
