x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
...
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

elf: Add PT_GNU_PROPERTY segment type
...
Linkers group input note sections with the same name into one output
note section with the same name. One output note section is placed in
one PT_NOTE segment. New linkers merge all input .note.gnu.property
sections into one output .note.gnu.property section with a single
NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older
linkers treat input .note.gnu.property section as a generic note section
and just concatenate all input .note.gnu.property sections into one
output .note.gnu.property section without merging them, we may
see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which
are invalid.
GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such
that linker sets the bit for non-relocatable outputs. But it isn't
sufficient:
1. It doesn't cover generic properties.
2. When -mx86-used-note=yes is passed to x86 assembler, the
GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED
property in object file and older linkers generate invalid
NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit
set.
I am proposing the following changes:
1. Add PT_GNU_PROPERTY segment type:
# define PT_GNU_PROPERTY (PT_LOOS + 0x474e553)
which covers .note.gnu.property section.
2. Remove GNU_PROPERTY_X86_UINT32_VALID.

x86: Don't remove empty GNU_PROPERTY_X86_UINT32_OR_AND properties
...
For GNU_PROPERTY_X86_COMPAT_ISA_1_USED and GNU_PROPERTY_X86_UINT32_OR_AND
properties, a bit in the output pr_data field is set if it is set in any
relocatable input pr_data fields and this property is present in all
relocatable input files. A missing property implies that its bits have
unknown values. When all bits in the the output pr_data field are zero,
this property should not be removed from output to indicate it has zero
in all bits.

x86: Update GNU_PROPERTY_X86_XXX macros
...
This patch updates GNU_PROPERTY_X86_XXX macros:
1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_AND_LO 0xc0000002
#define GNU_PROPERTY_X86_UINT32_AND_HI 0xc0007fff
2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000
#define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff
3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:
#define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000
#define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff
4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.
GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined. The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.
