Adhemerval Zanella 8d2d239cb7 Simplify tile assembly definitions
With tilepro removal, the uppercase instruction are not anymore
required to be defines as potentially macros.  This is a
mechanical change done by the following shell script:

---
INSNS="LD LD4U ST ST4 BNEZ BEQZ BEQZT BGTZ CMPEQI CMPEQ CMOVEQZ CMOVNEZ"

FILES=$(find sysdeps/tile sysdeps/unix/sysv/linux/tile -iname *.S)

for insn in $INSNS; do
  repl=$(echo $insn | tr '[:upper:]' '[:lower:]')
  sed -i 's/\b'$insn'\b/'$repl'/g' $FILES
done
---

Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with
and without the patch, there is no difference in generated binary with
a dissassemble.
