i386: Add -masm=intel profiling support [PR113122]

x86_function_profiler emits assembly directly into file and only emits
AT&T syntax.  The following patch adjusts it to emit MASM syntax
if -masm=intel.
As it doesn't use asm_fprintf, I can't use {|} syntax for the dialects.

I've tested using
for i in -mcmodel=large "-mcmodel=large -fpic" "" -fpic "-m32 -fpic" "-m32"; do
./xgcc -B ./ -c -O2 -fprofile $i -masm=att pr113122.c -o pr113122.o1;
./xgcc -B ./ -c -O2 -fprofile $i -masm=intel pr113122.c -o pr113122.o2;
objdump -dr pr113122.o1 > /tmp/1; objdump -dr pr113122.o2 > /tmp/2;
diff -up /tmp/1 /tmp/2; done
that the emitted sequences are identical after assembly.
