0c12614d1a A64/config.h: Split fastmem and page_table options. 
We might want to allocate different sizes for each of them.
e.g. for the unsafe fastmem approach without bounds checking.
Or for using the full 48bit adress range (with mirrors) by allocating our real arena as close to 1<<47 as possible.

06b31448aa emit_x64_vector: Changes to VectorSignedSaturatedDoublingMultiply 
* Return both the upper and lower parts of the multiply if required
* SSE2 does not support the pmuldq instruction, do sign correction to an unsigned result instead
* Improve port utilisation where possible (punpck instructions were a bottleneck)

55eaa16615 a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT 
Discovered by @Subv.
Fixes incomplete fix begun in 5a91c94dca47c9702dee20fbd5ae1f4c07eef9df.
That fix fails to take into account that LinkBlock doesn't update ticks until there
are no remaining ticks to be executed.

Test added to confirm fix.
