3447c82656 translate: Return by bool in helpers where applicable 
Gets rid of a bit of duplication regarding the early-out cases and makes
all helpers functions consistent (previously some had a return type of
bool, while others had a return type of void).

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.

4606a081c9 A64: The A64SetTPIDR IR instruction writes to a system register and should not be eliminated by the dead code elimination pass. 
Previously this instruction was alway eliminated, resulting in incorrect values for TPIDR_EL0.

3f602129f4 system: Ensure value of CNTPCT_EL0 is accurate 
Since we currently only update the host's tick count at the end of a
block, we force an end-of-block before executing a MRS %, CNTPCT_ELO
instruction.

9db6d1e98b translate_arm: Remove unnecessary rotr() function 
We already have RotateRight() in our common code, so we can remove this
function and replace it with it. We can also implement ArmExpandImm_C()
in terms of ArmExpandImm().

fcae4e2418 simd_three_different: Deduplicate common implementations 
Generally, the only difference between the signed variants and the
unsigned variants is whether or not we use a sign-extension or
zero-extension, so we can simply use common functions to implement both
cases without totally duplicating code twice here.
