function definitions for more informative error messages. No functionality change and all updated tests passed locally.
This update was done with the following bash script:
find test/CodeGen -name "*.ll" | \
while read NAME; do
echo "$NAME"
if ! grep -q "^; *RUN: *llc.*debug" $NAME; then
TEMP=`mktemp -t temp`
cp $NAME $TEMP
sed -n "s/^define [^@]*@\([A-Za-z0-9_]*\)(.*$/\1/p" < $NAME | \
while read FUNC; do
sed -i '' "s/;\(.*\)\([A-Za-z0-9_-]*\):\( *\)$FUNC: *\$/;\1\2-LABEL:\3$FUNC:/g" $TEMP
done
sed -i '' "s/;\(.*\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP
sed -i '' "s/;\(.*\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP
sed -i '' "s/;\(.*\)-NOT-LABEL:/;\1-NOT:/" $TEMP
sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP
mv $TEMP $NAME
fi
done

Print the high order register of a double word register operand.
In 32 bit mode, a 64 bit double word integer will be represented
by 2 32 bit registers. This modifier causes the high order register
to be used in the asm expression. It is useful if you are using
doubles in assembler and continue to control register to variable
relationships.
This patch also fixes a related bug in a previous patch:
case 'D': // Second part of a double word register operand
case 'L': // Low order register of a double word register operand
case 'M': // High order register of a double word register operand
I got 'D' and 'M' confused. The second part of a double word operand
will only match 'M' for one of the endianesses. I had 'L' and 'D'
be the opposite twins when 'L' and 'M' are.

Low order register of a double word register operand. Operands
are defined by the name of the variable they are marked with in
the inline assembler code. This is a way to specify that the
operand just refers to the low order register for that variable.
It is the opposite of modifier 'D' which specifies the high order
register.
Example:
main()
{
long long ll_input = 0x1111222233334444LL;
long long ll_val = 3;
int i_result = 0;
__asm__ __volatile__(
"or %0, %L1, %2"
: "=r" (i_result)
: "r" (ll_input), "r" (ll_val));
}
Which results in:
lui $2, %hi(_gp_disp)
addiu $2, $2, %lo(_gp_disp)
addiu $sp, $sp, -8
addu $2, $2, $25
sw $2, 0($sp)
lui $2, 13107
ori $3, $2, 17476 <-- Low 32 bits of ll_input
lui $2, 4369
ori $4, $2, 8738 <-- High 32 bits of ll_input
addiu $5, $zero, 3 <-- Low 32 bits of ll_val
addiu $2, $zero, 0 <-- High 32 bits of ll_val
#APP
or $3, $4, $5 <-- or i_result, high 32 ll_input, low 32 of ll_val
#NO_APP
addiu $sp, $sp, 8
jr $ra
If not direction is done for the long long for 32 bit variables results
in using the low 32 bits as ll_val shows.
There is an existing bug if 'L' or 'D' is used for the destination register
for 32 bit long longs in that the target value will be updated incorrectly
for the non-specified part unless explicitly set within the inline asm code.

Print the second half of a double word operand.
The include list was cleaned up a bit as well.
Also the test case was modified to test for both
big and little patterns.

inlineasm-cnstrnt-bad-r-1.ll is NOT supposed to fail, so it was removed. This resulted in the removal of a negative test (inlineasm-cnstrnt-bad-r-1.ll)

it appears to be breaking the bots.
This reverts commit 1b055ce320fa13f6f1ac81670d11b45e01f79876.

following description in the gnu sources:
Print $0 if operand is zero otherwise print the op normally.
