[PATCH]Fix newlib.wctype/twctrans.c compilation warning: implicit declaration of function 'toupper' & 'tolower'

[Renlin Li <renlin dot li at arm dot com>]

Hi all,

Recently, newlib/testsuite/newlib.wctype/twctrans.c fails to build for 
the following targets using latest GCC source.

aarch64-none-elf
arm-none-eabi
aarch64_be-none-elf

The following messages are produced:
newlib.wctype/twctrans.c compilation warning: implicit declaration of 
function 'toupper' & 'tolower' [-Wimplicit-function-declaration]

Instead, towupper and towloer should be called as wctype.h is included 
in the test case.

newlib regresstion test is done using aarch64-none-elf toolchain, no new 
issues.
Is it Okay to commit?
