Optimize: Make Bool_Array take less memory.

Browse Source 
Less memory means: less cache misses.
This reduces the execution time of gperf on large inputs by ca. 2.5%.

* src/bool-array.h (Bool_Array): For the _storage_array and
_iteration_number fields, use 'unsigned char' instead of 'unsigned int'.
* src/bool-array.icc (Bool_Array::Bool_Array, Bool_Array::clear: Update.
* src/bool-array.cc (Bool_Array::~Bool_Array): Update.
