Increase parse speed of long queries
------------------------------------
Key: CORE-6274
URL: http://tracker.firebirdsql.org/browse/CORE-6274
Project: Firebird Core
Issue Type: Improvement
Components: Engine
Affects Versions: 3.0.5, 4.0 Beta 1
Reporter: Adriano dos Santos Fernandes
With CORE-6246 tests, for example, parse is very slow because parser keeps
adding stack space in 16 increments, which makes lots of realloc and copies.
In a test (slow vm and debug build), changing YYSTACKGROWTH to 128 improves the
test from 33s to 7s.
