e802b90f31 Patch to clean up MSVC analysis warnings (bug 551690, r=edwsmith+ nnethercote+) 
(pushing for Bill Maddox)
The following appear to be false positives.  The patch adjusts the code in a
meaning-preserving way such that the analysis warnings no longer appear.  My
best guess is that the analysis does not take into account the discretenes of
integer arithmetic in analyzing relational operators.

nanojit/Assembler.cpp(2004)
nanojit/Nativei386.cpp(1214)

Here, an outer definition is indeed hidden, but it is dead at this point, and
the code is correct as it stands.  Stylistically, however, the hiding should be
avoided, as in the patch.

nanojit\LIR.cpp(671)

8ab25db2b6 Redo X64 asm_fneg to only allocate XMM regs, fix indirect calls, and revert asm_restore to old logic (bug 535706 r=nnethercote+) 
The code for indirect calls needed shuffling; we must freeResourcesOf() before
assigning the call address to a register.  The old code was just getting lucky,
and the regstate fixes tickled the latent bug.

asm_restore() can be stricter once we eliminate all cases where an F64 instruction
can be assigned to a GPR.  The only known remaining case is asm_quad which is used
for both LIR_float and LIR_quad, which should be fixed by bug 534310.

605b734ba8 (second try) Adds protect/unprotect API to CodeAlloc (bug 460993 r=nnethercote,rreitmai sr=gal) 
Removes calls to VMPI_setPageProtection from CodeAlloc, and adds a new
protect/unprotect API to CodeAlloc, along with an SPI for the vm to implement
actual page protection.

It is up to the VM to call codeAlloc->protect() before executing jit'd code,
but CodeAlloc will internally call unprotect() before modifying blocks, as code
is generated.  If the VM's implementation of allocCodePage allocates memory
as RWX, then the new protection api's can be ignored and the implementations
of markCodeChunkExec/Write can be empty functions.

A flag per code chunk is used so that only modified pages are unprotected and
reprotected.

CodeAlloc never calls VMPI_setPageProtection any more, so platform abstractions
for this can be encapsulated in the CodeAlloc SPI methods.

nanojit/avmplus.cpp was modified to call VMPI_setPageProtection on the platforms
that didn't already allocate code memory as RWX.  Since those callsites are platform
specific and the only place we call VMPI_setPageProtection, the code could be further
simplified.
