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.

04b4c8b0cf emit_x64_aes: Eliminate extraneous usage of a scratch register in EmitAESInverseMixColumns() 
We can just use the same register the data is in as the result register,

result.

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.

84affdb260 safe_ops: Avoid cases where shift bases are invalid with signed values 
For example, say the converted signed type is s64, shifting left  by 63
bits would be undefined behavior.

However, given an ASL is essentially the same behavior as an LSL
we can just use an unsigned type instead of converting to a signed type.

d0274f412a safe_ops: Avoid signed overflow in Negate() 
Negation of values such as -9223372036854775808 can't be represented in
signed equivalents (such as long long), leading to signed overflow.
Therefore, we can just invert bits and add 1 to perform this behavior
with unsigned arithmetic.

0ec8dac660 emit_x64: Remove FPSCR_RoundTowardsZero() virtual function from EmitContext struct 
This code was bugged in that we were comparing if the rounding mode was
not equal to rounding towards zero. Fortunately, however, nothing uses
this function anymore, and there's already the more general
FPSCR_RMode() available, so this can be removed entirely.

fd92e2f186 emit_x64: Add missing <array> include 
Commit 755adef62e504a8d616de9dda8937d2428a9471b introduced a helper
alias for std::array, eliminating the need to manually type out sizes
for them, however I forgot to add the include for <array>

f939bd0228 emit_x64_vector{_floating_point}: Add helper alias for sizing arrays relative to vector width 
Avoids needing to remember to specify the proper size of the arrays, all
that's needed is to specify the type of the array and the size will
automatically be deduced from it. This helps prevent potential oversized
or undersized arrays from being specified.
