[Bug]: CallConversion not catching malformed calls

Description

Related issue: #753

I'm currently printing out all callees within matchAndRewrite to verify names used by vast.

When converting hl.calls with signatures in form \01_xx, CallConversion fails to produce any output.

Steps to Reproduce

Compiled test.c:

#include <fcntl.h>
#include <unistd.h>

void test(int name) {
    close(name);
}

vast-front -DHAVE_CONFIG_H -I. -g -O2 -c -o test.mlir test.c -vast-emit-mlir=hl -vast-simplify -vast-show-locs -vast-loc-attrs

Then vast-detect-parsers test.mlir --vast-hl-to-parser -reconcile-unrealized-casts -o vast.parser.mlir.

matchAndRewrite also fails to catch non-malformed calls.

Steps to Reproduce

Compile lib/chdir-long.c of gzip (1.10) to hl, then to parser. cdb_advance_fd call is missing.
