[PATCH] RISC-V: Support GNU indirect functions.

For now, the following relocations are supported for IFUNC in linker,
* R_RISCV_32 or R_RISCV_64
Store the IFUNC symbol into the data section. Consider the ifunc-10.s
or others in the ld testsuite.
* R_RISCV_HI20 and R_RISCV_LO12_I/S
The LUI + ADDI/LW/SW patterns. The absolute access relocation. Originally,
I thought we didn't need to care about them, until I noticed that the
ld test suites "Build pr23169a" and "Build pr23169d" needed them. The
test suites are in the ld/testsuite/ld-ifunc/ and need compiler
support. I think the medlow model without -fPIC compiler option and
-shared linker option will possibly generate them.
* R_RISCV_CALL or R_RISCV_CALL_PLT
I don't think the RISC-V compiler will generate R_RISCV_JAL directly
to jump to an IFUNC. Besides, I disable the relaxations for the
relocation referenced to IFUNC, so just handling the R_RISCV_CALL and
R_RISCV_CALL_PLT should be enough. We also need to allocate the PLT
entry for the R_RISCV_CALL if it is referenced to IFUNC symbol.
For now, GNU GCC and Binutils handle the R_RISCV_CALL and R_RISCV_CALL_PLT
separately. But they can (should) be handled identically, since RISC-V lld
had made the same improvement. And so had GNU AARCH64, they has only
R_AARCH64_CALL26 for calls. It will affect the current IFUNC implementation
in this patch. Therefore, I prefer to improve both of them in the future
patches, if everyone is OK.
* R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO12_I/S
LA/LLA pattern with local fPIC ifunc symbol, or any non-PIC ifunc
symbol. The PC-relative relocation.
* R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO12_I/S
LA pattern with global PIC ifunc symbol. Also check if it is possible to
generate the PLT entry for IFUNC GOT reference. This saves the PLT spaces,
and also reduces the overload of glibc.
Besides, consider the two commits,
1. cebd6b8ac1c5a2a847a50e3efe932ff2d0867b3e
IFUNC: Update IFUNC resolver check with DT_TEXTREL.
2. 3084d7a27b8e4d13f0fdd0fac62ffadc9c2223b5
ELF: Add _bfd_elf_add_dynamic_tags
These two commits will warn users that they should recompile their code
with -fPIC or -fPIE, otherwise the GNU indirect functions with DT_TEXTREL
may result in a segfault at runtime. R_RISCV_HI20 and R_RISCV_32/64 should
be fine here, since we don't allow the former when generating the shared
library or PIE executable. And the later are used in the data section rather
than the code for now. But R_RISCV_CALL and R_RISCV_PCREL_HI20 may cause the
warning. Consider the ifunc-2 testsuite in the ld/testsuite/ld-riscv-elf/.
For the ifunc-2, the dynamic relocation, which cause the TEXTREL, are all
R_RISCV_NONE and do nothing in the glibc or other dynamic loaders.
I believe this can be resolved by changing some checking rules in the
riscv_elf_check_relocs.
bfd/
* elfnn-riscv.c: Include "objalloc.h" since we need objalloc_alloc.

allocate_local_ifunc_dynrelocs to handle the IFUNC symbols if they
are defined and referenced in a non-shared object.
(allocate_ifunc_dynrelocs): New function. Allocate space in .plt,
.got and associated reloc sections for ifunc dynamic relocs.
(allocate_local_ifunc_dynrelocs): Likewise, but for local ifunc
dynamic relocs.

referenced to IFUNC symbols.
(riscv_elf_size_dynamic_sections): Updated.

including fill the PLT and GOT entries for IFUNC symbols.
