Fix trampolines search code for conditional branches
...
For conditional branches that need more than one trampoline to reach its
target assembler couldn't always find suitable trampoline because
post-loop condition check was placed inside the loop, resulting in
premature loop termination. Move check outside the loop.
This fixes the following build errors seen when assembling huge files
produced by gcc:
Error: jump target out of range; no usable trampoline found
Error: operand 1 of 'j' has out of range value '307307'

Fix alignment for the first section frag on xtensa
...
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.
