Function types without prototypes can arise when mangling a function type
within an overloadable function in C. We mangle these as the absence of
any parameter types (not even an empty parameter list).

[LAA] Remove unused pointer partition argument from getNumberOfChecks, NFC

[LAA] Make the set of runtime checks part of the state of LAA, NFC
This is the full set of checks that clients can further filter. IOW,
it's client-agnostic. This makes LAA complete in the sense that it now
provides the two main results of its analysis precomputed:
1. memory dependences via getDepChecker().getInsterestingDependences()
2. run-time checks via getRuntimePointerCheck().getChecks()
However, as a consequence we now compute this information pro-actively.
Thus if the client decides to skip the loop based on the dependences
we've computed the checks unnecessarily. In order to see whether this
was a significant overhead I checked compile time on SPEC2k6 LTO bitcode
files. The change was in the noise.
The checks are generated in canCheckPtrAtRT, at the same place where we
used to call groupChecks to merge checks.

Summary:
With InstAlias, we don't need to print the _e32 portion of the mnemonic
when we print the $dst operand. This change makes it possible to
include vcc in the asm string when we switch VOPC over to having
implicit vcc defs.
