Linking object files produced by partial linking with link-time
relaxation enabled sometimes fails with the following error message:
dangerous relocation: call8: misaligned call target: (.text.unlikely+0x63)
This happens because no basic block with an XTENSA_PROP_ALIGN flag in the
property table is generated for the first basic block, even if the
.align directive is present.
It was believed that the first frag alignment could be derived from the
section alignment, but this was not implemented for the partial linking
case: after partial linking first frag of a section may become not
first, but no additional alignment frag is inserted before it.
Basic block for such frag may be merged with previous basic block into
extended basic block during relaxation pass losing its alignment
restrictions.
Fix this by always recording alignment for the first section frag.

There's no real need to emit these always: They're needed only if we
indeed want to emit a localized symbol. Hence defer emission until we
at least did the basic early checks that would lead to no such symbol

If a 16-bit offset is not suitable for the instruction we're

ADDRESS_ADDI_INSN. Make the M_LI_DD code fall through into the
M_L_DAB code once the address has been constructed. For double load
and store macros, again handle the 16-bit offset case first.
If the second register cannot be accessed from the same high
part as the first, load it into AT using ADDRESS_ADDI_INSN.
Fix the handling of LD in cases where the first register is the
same as the base. Also handle the case where the offset is
not 16 bits and the second register cannot be accessed from the
same high part as the first. For unaligned loads and stores,
fuse the offbits == 12 and old "ab" handling. Apply this handling
whenever the second offset needs a different high part from the first.
Construct the offset using ADDRESS_ADDI_INSN where possible,
for offbits == 16 as well as offbits == 12. Use offset_reloc
when constructing the individual loads and stores.

Make current with UA2011 specification.
Add an F_PREFERRED opcode flag that indicates a preferred alias
when multiple aliases for the same opcode exists.
For 'lzd':
Add 'lzcnt' as primary instruction, and make 'lzd' an alias.
Add 'ldtw', 'ldtwa', 'sttw', 'sttwa':
The modern opcode for for 'ldd', 'ldda', 'std', and 'stda' on
integer registers. Mark the latter now as aliases.
For 'flush':
Support "[address]" syntax as well as plain "address".
Rework 'mov' aliases for 'wr':
Eliminate bogus three operand moves, and encode the
instructions properly for the "mov REG, %ASR" cases,
specifically we should encode the register in rs2 not rs1 as
per The SPARC V8 Architecture Manual.
Add missing cbcond aliases:
c{w,x}bz, c{w,x}blu, c{w,x}bnz, c{w,x}bgeu
Add 'd' suffix VIS logical ops:
The primary opcode for 'fzero' is now 'fzerod' (compare with
'fzeros'), for example. And thus 'fzero' is now an alias.
Add modern opcodes for condition code setting edge instructions:
They are now edgeN{,l}cc instead of plain edgeN{,l}.
Add modern opcodes for VIS comparisons:
All VIS comparisons now start with prefix "fp", retain the
older variants as aliases.
The signed variants for equal and not-equal have "u" aliases
to show that these comparisons are equally suited for unsigned
compares.
Update existing test cases as needed, and add several new ones.

mark existing mnenomics as aliases. Add "cc" suffix to edge
instructions generating condition codes, mark existing mnenomics
