9efa35156a Add NJ_USES_QUAD_CONSTANTS mode (and i386 implementation) to allow for faster float constants on CPUs without useful 64-bit immediates. Instead of allocating stack space for the constants (and filling them in via move-immediates), allocate data space for them and embed literal pointers into the code stream.

5be99c7ad2 Bug 500466 - avmshell crashes on P3 cpu machine with JIT enabled (r+nnethercote,edwsmith) 
Copy x86 CPU detection code from jstracer into Nativei386;
allowing hosts to share the common code.

One potential issue with this patch is that the detection code is
executed each time an Assembler object is created.

If it becomes an issue, it might be worthwhile to add a tri-state
to config in order to capture the value post-test.

d7a89e77b5 Add LIR_jtbl instruction, and patch up lirasm to remove LIR_ji (bug 465582 r=nnethercote+, rreitmai+) 
new opcode: LIR_jtbl.  jtbl takes a uint32_t index and a table of label
references (LIns**), representing a jump to one of the labels.

the index must be in range (range checking is not included in the opcode).

the table is allocated in memory at least as long lived as the LIR; this is
accomplished by doing the allocation from the same Allocator used by LirBuffer.

In the x86 backend, this is implemented with a simple jmp [R*4+ADDR] where ADDR
is the address of the table.  I added a new dataAllocator (Allocator&)
parameter to Assembler, which is used for allocating data along with code (data
& code have same lifetime).  The x86 backend allocates the final table of
addresses from this allocator and embeds the pointer to the table in code.

In other backends more than one instruction must be used due to limited range
of the constant part of the addressing mode (ppc, arm), or non-support for
full-range pc-relative indexing (x64, ppc64).

Anyone generating LIR code for use with LIR_jtbl must also generate a
LIR_regfence instruction after each label reachable by a forwards edge
from LIR_jtbl.  This is to workaround the register allocator's inability
to merge register states between 2 or more pre-existing targets.  LIR_regfence
is not required for backwards edges.
