x86: Implement SMEP and SMAP

This patch implements Supervisor Mode Execution Prevention (SMEP) and
Supervisor Mode Access Prevention (SMAP) for x86. The purpose of the
patch, obviously, is to help kernel developers debug the support for
those features.

i386: -cpu help: remove reference to specific CPUID leaves/registers

The -cpu configuration interface is based on a list of feature names or
properties, on a single namespace, so there's no need to mention on
which CPUID leaf/register each flag is located....

i386: cpu: eliminate duplicate feature names

Instead of having duplicate feature names on the ext2_feature array for
the AMD feature bit aliases, we keep the feature names only on the
feature_name[] array, and copy the corresponding bits to
cpuid_ext2_features in case the CPU vendor is AMD....

i386: cpu: replace EXT2_FEATURE_MASK with CPUID_EXT2_AMD_ALIASES

Both constants have the same value, but CPUID_EXT2_AMD_ALIASES is
defined without using magic numbers.

i386: kvm: use a #define for the set of alias feature bits

Instea of using a hardcoded hex constant, define CPUID_EXT2_AMD_ALIASES
as the set of CPUID[8000_0001].EDX bits that on AMD are the same as the
bits of CPUID1.EDX.

i386: kvm: bit 10 of CPUID[8000_0001].EDX is reserved

Bit 10 of CPUID[8000_0001].EDX is not defined as an alias of
CPUID1.EDX10, so do not duplicate it on
kvm_arch_get_supported_cpuid().

Emit debug_insn for CPU_LOG_TB_OP_OPT as well.

For all targets that currently call tcg_gen_debug_insn_start,
add CPU_LOG_TB_OP_OPT to the condition that gates it.

This is useful for comparing optimization dumps, when the
pre-optimization dump is merely noise....
