Complement commit ffe54b3798 ("Pad sections according to current
script FILL.") and add a FILL script statement test for targets that
impose the minimum alignment of more than 2**2 for the `.text' section.
These targets include IA-64 targets, MIPS targets other than bare-metal
ELF and VxWorks, TILE-Gx targets, TILEPro targets and X86-64 PE targets.
Use the `notarget' tag for configuration triplets that are incompatible
with the new test, but are supported by the existing FILL test, and
`xfail' for ones that have issues due to section alignment or padding
with both tests. Make a complementary change to the existing FILL test,
removing the following test issues:
arm-epoc-pe -FAIL: ld-scripts/fill
mips-elf -XPASS: ld-scripts/fill
mips-img-elf -XPASS: ld-scripts/fill
mips-mti-elf -XPASS: ld-scripts/fill

mips-vxworks -XPASS: ld-scripts/fill

mipsel-mti-elf -XPASS: ld-scripts/fill
mipsel-vxworks -XPASS: ld-scripts/fill

mipsisa32el-elf -XPASS: ld-scripts/fill
mipsisa64-elf -XPASS: ld-scripts/fill
mipsisa64el-elf -XPASS: ld-scripts/fill
tilegx-linux -FAIL: ld-scripts/fill
tilepro-elf -FAIL: ld-scripts/fill
tx39-elf -XPASS: ld-scripts/fill
