tc-i386.c: store encoded instructions in unsigned char[]
char can be a signed type, and some of the values in these arrays are greater than 0x80 which means they are outside of the range a signed char can store. Fortunately it seems most compilers handle this in the obvious way by storing the same bits as a negative number, but this is wierd and easily fixed. gas/ChangeLog: 2016-03-20 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * tc-i386.c (f32_1): Change type to unsigned char[].
