[scudo] Minor changes and refactoring

Summary:
This is part of D31947 that is being split into several smaller changes.

This one deals with all the minor changes, more specifically:
- Rename some variables and functions to make their purpose clearer;
- Reorder some code;
- Mark the hot termination incurring checks as `UNLIKELY`; if they happen, the
  program will die anyway;
- Add a `getScudoChunk` method;
- Add an `eraseHeader` method to ScudoChunk that will clear a header with 0s;
- Add a parameter to `allocate` to know if the allocated chunk should be filled
  with zeros. This allows `calloc` to not have to call
  `GetActuallyAllocatedSize`; more changes to get rid of this function on the
  hot paths will follow;
- reallocate was missing a check to verify that the pointer is properly
  aligned on `MinAlignment`;
- The `Stats` in the secondary have to be protected by a mutex as the `Add`
  and `Sub` methods are actually not atomic;
- The software CRC32 function was moved to the header to allow for inlining.

[mips][msa] Mask vectors holding shift amounts

Masked vectors which hold shift amounts when creating the following nodes:
ISD::SHL, ISD::SRL or ISD::SRA.
Instructions that use said nodes, which have had their arguments altered are
sll, srl, sra, bneg, bclr and bset.

For said instructions, the shift amount or the bit position that is
specified in the corresponding vector elements will be interpreted as the
shift amount/bit position modulo the size of the element in bits.

The problem lies in compiling with -O2 enabled, where the instructions for
formats .w and .d are not generated, but are instead optimized away.
In this case, having shift amounts that are either negative or greater than
the element bit size results in generation of incorrect results when
constant folding.

We remedy this by masking the operands for the nodes mentioned above before
actually creating them, so that the final result is correct before placed
into the constant pool.

Summary:
The thread order test fails sometimes my machine independently of standalone
build.

From testing both standalone and in-tree build, I see I configured it wrong.

The other hypothesis for an issue is that cold starts can interfere with whether
record unwriting happens. Once this happens more than once, we can naively
FileCheck on the wrong test output, which compounds the issue.

While "rm blah.* || true" will print to stderr if the glob can't expand, this is
mostly harmless and makes sure earlier failing tests don't sabotage us.

Example failure:

---

  nonstop-tsc:     true

7 years agoTurn symbolization on for ASan unit test.

Turn symbolization on for ASan unit test.

Summary:
On PowerPC and ARM (possibly, need to verify), couple tests involving
pthread_exit fail due to leaks detected by LSan. pthread_exit tries
to perform unwinding that leads to dlopen'ing libgcc_s.so. dlopen
mallocs "libgcc_s.so" string which confuses LSan, it fails to
realize that this allocation happens in dynamic linker and should
be ignored.
Symbolized leak report is required to define a suppression for this
known problem.

[SCEV] Make SCEV or modeling more aggressive.

Use haveNoCommonBitsSet to figure out whether an "or" instruction
is equivalent to addition. This handles more cases than just
checking for a constant on the RHS.
