Quick hack to fix interpretation of patterns in Ltac.
Interpretation of patterns in Ltac is essentially flawed. It does a roundtrip
through the pretyper, and relies on suspicious flagging of evars in the evar source
field to recognize original pattern holes. After the pattern_of_constr function
was made evar-insensitive, it expanded evars that were solved by magical side-effects
of the pretyper, even if it hadn't been asked to perform any heuristics.
We backtrack on the insensitivity of the pattern_of_constr function. This may have
a performance penalty in other dubious code, e.g. hints. In the long run we should
get rid of the pattern_of_constr function.
