The testcase is assuming that the parameter being watched isn't being
modified. But the way the test program is written, this is not true
at all. So this changes fixes the code to still reference the variable,
but in a way that does not modify its value.

The ada-lang.c:compare_names function returns the wrong value
when the first string starts with the same contents as the second
string, followed by '_' and then some characters that do not make
a symbol name suffix. For instance:
string1 = "generics__test_generics__instance__print"
string2 = "generics__test_generics"
In that case, compare_names (string1, string2) return -1, when
clearly, string1 is greater than string2.
A consequence of this problem is that GDB may fail to lookup
"generics.test_generics" from our partial symtabs, because
partial symbols are ordered by strcmp_iw_ordered:
(gdb) b generics.test_generics
Function "generics.test_generics" not defined.
Make breakpoint pending on future shared library load? (y or [n])

The read_frame_register_value function as it was implemented introduced
a regression on big-endian targets. The problem appears when trying to
get the value of an entity stored inside a register, and when the size
of the entity is smaller than the size of the register. In that case,
we were always reading the first N bytes of the register, which is wrong
for big-endian architectures, where we need to read the last N bytes of
the register.

register on big-endian architectures.
