+/*The allocator handles all allocation of executable memory. Since the two-pass

+  allocator allows memory to be provided as and when required.
+  
+  The allocator provides a block size of a little under 1 kB (slightly lower to
+  limit cache aliasing). Each generated codeblock is allocated one block by default,
+  and will allocate additional block(s) once the existing memory is sorted. Blocks
+  are chained together by jump instructions.
+  
+  Due to the chaining, the total memory size is limited by the range of a jump
+  instruction. ARMv7 is restricted to +/- 32 MB, ARMv8 to +/- 128 MB, x86 to
+  +/- 2GB. As a result, total memory size is limited to 32 MB on ARMv7*/
