[arm] Implement usadv16qi and ssadv16qi standard names
This patch implements the usadv16qi and ssadv16qi standard names for arm.
The V16QImode variant is important as it is the most commonly used pattern:
reducing vectors of bytes into an int.
The midend expects the optab to compute the absolute differences of operands 1
and 2 and reduce them while widening along the way up to SImode. So the inputs
are V16QImode and the output is V4SImode.
I've based my solution on Aarch64 usadv16qi and ssadv16qi standard names
current implementation (r260437). This solution emits below sequence of
instructions:
VABDL.u8 tmp, op1, op2 # op1, op2 lowpart
VABAL.u8 tmp, op1, op2 # op1, op2 highpart
VPADAL.u16 op3, tmp
So, for the code:
$ arm-none-linux-gnueabihf-gcc -S -O3 -march=armv8-a+simd -mfpu=auto -mfloat-abi=hard usadv16qi.c -dp
#define N 1024
unsigned char pix1[N];
unsigned char pix2[N];
int
foo (void)
{
int i_sum = 0;
int i;
for (i = 0; i < N; i++)
i_sum += __builtin_abs (pix1[i] - pix2[i]);
return i_sum;
}
we now generate on arm:

compiler: make escape analysis work with imported inlineable functions
The escape analysis was written before we import inlineable
function bodies, and in some places it skipped functions that are
not in the local package. Now that there are imported function
bodies, make the escape analysis work with them.
Note that it is necessary for the escape analysis to run on
imported function bodies, even if they are already tagged. The
tags only have the information of the parameters (receiver,
results), but not the internal nodes, e.g. local variables. We
still need to do the analysis to get all the information. (In the
future maybe we could export/import escape info for internal
nodes also, then we don't need to redo the analysis.)
Also add assertions to ensure that if we analyze the same
function in multiple places, they'd better agree with each other.

The number of errors differs between C++14 and C++17 modes, so the fixed
test uses dg-excess-errors to match any number of them. The precise
