This is PR 8/18 from the sygus comp 2018 branch (https://github.com/ajreynol/CVC4/tree/sygusComp2018-2).
I am not sure how it is possible in any circumstance that the complication in the comment I am deleting would ever happen, without doing something very strange. I think it is referring to some sort of inter-dependence between macro expansion + beta-reductions. This should not concern the rewriter. Here is the commit that introduced it: bdaa304.

* Fixes --hide-zero-stats (and really skips the 0 values)
* Removes the additional newline after each statistic
* Introduces theory::getStatsPrefix(TheoryId) to generate consistent
prefixes for statistics based on the theory id
(e.g., THEORY_BV -> "theory::bv").

Adds missing override keywords.

Removing more miscellaneous throw specifiers.

This clarifies the memory ownership of EqProofs.

CVC4 was implementing multiple, slightly different hash functions for
pairs. With pull request #1157, we have a decent generic hash function
for pairs. This commit replaces the existing hash function
implementations with a typedef of the generic hash function.

* Extend quantifier-free UF solver to higher-order. This includes an extensionality inference, and lazy conversion from APPLY_UF to HO_APPLY terms.Implements collectModelInfo and theory combination for HO_APPLY terms.
* Update comments, minor changes to functions. Update APPLY_UF skolem to be user-context dependent.
* Remove unused NodeList

This consists of a binary apply symbol HO_APPLY that returns the result of applying its first argument to its second argument. Update the UF rewriter to ensure that non-standard APPLY_UF applications are rewritten into curried applications of HO_APPLY.

This is required for reasoning higher-order, since we may have equalities between functions, which are operators of APPLY_UF terms.
This commit gets around the previous 1% slowdown by modifying the changes to the equality engine to be minimal impact. Previously the "isInternal" flag could be reset to false after a term is marked as internal=true. This provides an interface for whether operators of a kind should be marked as internal=false from the start. When using higher-order, APPLY_UF operators will be marked as being external when the higher-order option ufHo is set to true.
This has <.001% impact on performance on QF smtlib : https://www.starexec.org/starexec/secure/details/job.jsp?id=24445
