target-i386: cpu: Fix potential buffer overrun in get_register_name_32()

Spotted by Coverity,
x86_reg_info_32[] is CPU_NB_REGS32 elements long, so accessing
x86_reg_info_32[CPU_NB_REGS32] will be one element off array.

target-i386: Update model values on Conroe/Penryn/Nehalem CPU models

The CPUID model values on Conroe, Penryn, and Nehalem are too
conservative and don't reflect the values found on real Conroe, Penryn,
and Nehalem CPUs.

This causes at least one known problems: Windows XP disables sysenter...

target-i386: Set level=4 on Conroe/Penryn/Nehalem

The CPUID level value on Conroe, Penryn, and Nehalem are too low. This
causes at least one known problem: the -smp "threads" option doesn't
work as expect if level is < 4, because thread count information is...

target-i386: Fix aflag logic for CODE64 and the 0x67 prefix

The code reorganization in commit 4a6fd938 broke handling of PREFIX_ADR.
While fixing this, tidy and comment the code so that it's more obvious
what's going on in setting both aflag and dflag.

The TARGET_X86_64 ifdef can be eliminated because CODE64 expands to the...

target-i386: Fix mask of pte index in memory mapping

Function walk_pte() needs pte index to calculate virtual address.
However, pte index of PAE paging or IA-32e paging is 9 bit, so the mask
should be 0x1ff.

target-i386: fix abort on bad PML4E/PDPTE/PDE/PTE addresses

The code used to walk IA-32e page-tables, and possibly PAE page-tables,
uses the bit mask ~0xfff to get the next PML4E/PDPTE/PDE/PTE address.

However, as we use a uint64_t to store the resulting address, that mask...

target-i386: n270 can MOVBE

The Atom core (cpu name "n270" in QEMU speak) supports MOVBE. This is
needed when booting 3.8 and later linux kernels built with the MATOM
target because we require MOVBE in order to boot properly now.
