[abi] AsmJit v1.18 - performance and memory footprint improvements

Browse Source 
* Refactored the whole codebase to use snake_case convention to
    name functions and variables, including member variables.
    Class naming is unchanged and each starts with upper-case
    character. The intention of this change is to make the source
    code more readable and consistent across multiple projects
    where AsmJit is currently used.

  * Refactored support.h to make it more shareable across projects.

  * x86::Vec now inherits from UniVec

  * minor changes in JitAllocator and WriteScope in order to make
    the size of WriteScope smaller

  * added ZoneStatistics and Zone::statistics() getter

  * improved x86::EmitHelper to use tables instead of choose() and
    other mechanisms to pick between SSE and AVX instructions

  * Refactored the whole codebase to use snake_case convention for
    for functions names, function parameter names, struct members,
    and variables

  * Added a non-owning asmjit::Span<T> type and use into public API
    to hide the usage of ZoneVector in CodeHolder, Builder, and
    Compiler. Users now only get Span (with data and size), which
    doesn't require users to know about ZoneVector

  * Removed RAWorkId from RATiedReg in favor of RAWorkReg*

  * Removed GEN from LiveInfo as it's not needed by CFG construction
    to save memory (GEN was merged with LIVE-IN bits). The remaining
    LIVE-IN, LIVE-OUT, and KILL bits are enough, however KILL bits may
    be removed in the future as KILL bits are not needed after LIVE-IN
    and LIVE-OUT converged

  * Optimized the representation of LIVE-IN, LIVE-OUT, and KILL bits
    per block. Now only registers that live across multiple basic
    blocks are included here, which means that virtual registers that
    only live in a single block are not included and won't be overhead
    during liveness analysis. This optimization alone can make liveness
    analysis 90% faster depending on the code generated (more virtual
    registers that only live in a single basic block -> more gains)

  * Optimized building liveness information bits per block. The new
    code uses an optimized algorithm to prevent too many traversals
    and uses a more optimized code for a case in which not too many
    registers are used (it avoids array operations if the number of
    all virtual registers within the function fits a single BitWord)

  * Optimized code that computes which virtual register is only used
    in a single basic block - this aims to optimize register allocator
    in the future by using a designed code path for allocating regs
    only used in a single basic block

  * Reduced the information required for each live-span, which is used
    by bin-packing. Now the struct is 8 bytes, which is good for a lot
    of optimizations C++ compiler can do

  * Added UniCompiler (ujit) which can be used to share code paths
    between X86, X86_64, and AArch64 code generation (experimental).
