[PATCH 11/46] kernel: Add prototype declaration in kernel/gcov/base.c

[Rashika Kheria]

Add prototype declarations of functions in kernel/gcov/base.c. These
functions are required by GCC builtins and hence can not be removed
despite of their unreferenced appearance in kernel source.

This eliminates the following warning in kernel/gcov/base.c:
kernel/gcov/base.c:30:6: warning: no previous prototype for â__gcov_initâ [-Wmissing-prototypes]
kernel/gcov/base.c:58:6: warning: no previous prototype for â__gcov_flushâ [-Wmissing-prototypes]
kernel/gcov/base.c:64:6: warning: no previous prototype for â__gcov_merge_addâ [-Wmissing-prototypes]
kernel/gcov/base.c:70:6: warning: no previous prototype for â__gcov_merge_singleâ [-Wmissing-prototypes]
kernel/gcov/base.c:76:6: warning: no previous prototype forâ__gcov_merge_deltaâ [-Wmissing-prototypes]
kernel/gcov/base.c:82:6: warning: no previous prototype for â__gcov_merge_iorâ [-Wmissing-prototypes]
