5f0117385e Refs #154. Fixed a SEGFAULT bug of dgemv_t when m is very large.
It overflowed the internal buffer. Thus, we split vector x into blocks when m is very large.

Thank @wangqian for this patch.

c852ce3981 Ref #65. Fixed 64-bit Windows calling convention bug in cdot and zdot.
According to 64-bit Windows calling convention, the return value is in %rax instead of %xmm0 in cdot kernel.
In zdot, the caller allocates a memory space for return value and sets this memory address to the first hidden parameter. Thus, the callee (zdot) should assign the result to this memory space and return the memory address in %rax.
