Arnold Schwaighofer 90774f3c8f ARM cost model: Increase the cost for vector casts that use the stack

Increase the cost of v8/v16-i8 to v8/v16-i32 casts and truncates as the backend
currently lowers those using stack accesses.

This was responsible for a significant degradation on
MultiSource/Benchmarks/Trimaran/enc-pc1/enc-pc1
where we vectorize one loop to a vector factor of 16. After this patch we select
a vector factor of 4 which will generate reasonable code.

unsigned char cle[32];

void test(short c) {
  unsigned short compte;
  for (compte = 0; compte <= 31; compte++) {
    cle[compte] = cle[compte] ^ c;
  }
}

[asan] use 4Tb of address space for the asan allocator instead of 1Tb. This increases the memory available for a single size class from 16Gb to 64Gb. The total VM footprint becomes 20Tb
