Do you have properly setup exceptions vector table?
Do you have properly configure MEMAP?
Are you sure that you enter main() with "I" bit in
CPSR cleared?

Here are some other minor remarks:

The code:
PINSEL0 |= 0x00000020;
is better(safer) to look like this:
PINSEL0 = (PINSEL0 & (~0x30)) | 0x00000020;

Here you don't need read-modify-write:
VICIntEnable |= VIC_BIT(VIC_TIMER0);
Simple put:
VICIntEnable = VIC_BIT(VIC_TIMER0);
