* Reworked register operands - all vector registers are now
platform::Vec deriving from UniVec (universal vector operand),
additionally, there is no platform::Reg, instead asmjit::Reg
provides all necessary features to make it a base register for
each target architecture
* Reworked casting between registers - now architecture agnostic
names are preferred - use Gp32 instead of Gpd or GpW, Gp64
instead of Gpq and GpX, etc...
* Reworked vector registers and their names - architecture
agnostic naming is now preferred Vec32, Vec64, Vec128, etc...
* Reworked naming conventions used across AsmJit - for clarity
Identifiers are now prefixed with the type, like sectionId(),
labelId(), etc...
* Reworked how Zone and ZoneAllocator are used across AsmJit,
prefering Zone in most cases and ZoneAllocator only for
containers - this change alone achieves around 5% better
performance of Builder and Compiler
* Reworked LabelEntry - decreased the size of the base entry
to 16 bytes for anonymous and unnamed labels. Avoided an
indirection when using labelEntries() - LabelEntry is now
a value and not a pointer
* Renamed LabelLink to Fixup
* Added a new header <asmjit/host.h> which would include
<asmjit/core.h> + target tools for the host architecture,
if enabled and supported
* Added new AArch64 instructions (BTI, CSSC, CHKFEAT)
* Added a mvn_ alternative of mvn instruction (fix for Windows
ARM64 SDK)
* Added more AArch64 CPU features to CpuInfo
* Added better support for Apple CPU detection (Apple M3, M4)
* Added a new benchmarking tool asmjit_bench_overhead, which
benchmarks the overhead of CodeHolder::init()/reset() and
creating/attaching emitters to it. Thanks to the benchmark the
most common code-paths were optimized
* Added a new benchmarking tool asmjit_bench_regalloc, which
aims to benchmark the cost and complexity of register allocation.
* Renamed asmjit_test_perf to asmjit_bench_codegen to make it
clear what is a test and what is a benchmark
