This patch updates multiple opcode prefix processing:
1. Always print prefix together with bad opcode.
2. Since the last seen segment register prefix is active, we only print
the active segment register in the memory operand.
3. The 0xf2 and 0xf3 prefixes take precedence over the 0x66 prefix as the
opcode prefix. Also the last of the 0xf2 and 0xf3 prefixes wins.
4. Ignore invalid 0xf2/0xf3 prefixes if they aren't mandatory.

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.

Check 8 and 16 bit PCREL fixes for overflow, since we bypass the
later overflow checks in write.c. Direct relocs are left alone,
as gcc has been known to take advantage of the silent overflows
when comparing addresses to constant ranges.

so that a gas_assert was being triggered. The patch replaces the assert with an error
