Fix warnings when compiling codegen_*.c
...
Patch from davefiddes. Original commit message :
This fixes the following warnings:
codegen_allocator.c:
- implict function declaration of rand() due to missing stdlib.h
codegen_backend_x86-64.c:
- implict function declaration of malloc() due to missing stdlib.h
- unused variables in codegen_backend_init()
- invalid typecast in use of host_x86_CALL()
codegen_backend_x86-64-uop.c:
- Remove unused variable declarations in codegen_CALL_FUNC_RESULT(),
codegen_LOAD_SEG(), codegen_OR_IMM(), codegen_XOR() and codegen_XOR_IMM()
- Move debug only variable declarations under the debug conditional define in
codegen_CALL_FUNC_RESULT(), codegen_LOAD_SEG(), codegen_MEM_LOAD_SINGLE(),
codegen_MEM_LOAD_DOUBLE(), codegen_MEM_STORE_SINGLE(),
codegen_MEM_STORE_DOUBLE()
codegen_reg.c:
- Change (int) typecasts to the correct (intptr_t) for small values stored
in a pointer. This fixes a series of 64-bit compilation warnings.
Tests:
- Build with no warnings on Fedora 32 with gcc 10.1
- Boot a Win98 machine with dynamic compilation enabled

XMM registers are not preserved across function calls, and should be flushed & discarded by the recompiler prior to calling external functions. Fixes graphics issues in some games (eg World Cup 98 title/menus).

Add new codegen memory allocator. This allows the recompiler to allocate memory from a central pool as required. This central pool is by default 64 MB on x86, x86-64 and ARMv8, and 32 MB on ARMv7.
...
The current design does not allow for ARMv8 literal pools, therefore these have been removed.

Further reductions to codeblock_t size - replace link pointers with uint16_t block indicies, shrink ins to uint8_t, remove endpc. codeblock_t now fits in a 64-byte cacheline on 32-bit platforms.
