Define __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS again.

Browse source 
Revert commit f6abaf7a40 (gdb: no longer define
__STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS), with the tweak suggested
in that commit's log: the macros are now defined before any system
header is included.

This should fix AIX:

"On some hosts that predate C++11, when using C++ one must define
__STDC_CONSTANT_MACROS to make visible the definitions of constant
macros such as INTMAX_C, and one must define __STDC_LIMIT_MACROS to
make visible the definitions of limit macros such as INTMAX_MAX.".
Must do this before including any system header, since system
headers may include stdint.h. */
