This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
This mainly does two things,
1. Removes spaces after commas
2. Elides "0x" and leading zeros in most contexts
Remaining differences are:
1. objdump always has memory size annotations
We lack these and probably have some annotations wrong
2. Boolean check names
We use jump-zero, while objdump uses jump-equal for example
3. We sometimes add "00 00" symbols, which objdump elides
4. We always demangle (This is a good thing)
5. We always resolve relocations (This is a good thing)
6. We seem to detect some symbols differently/incorrectly
This allows disassembly of binaries with SSE2 instructions in them.
SSE2 also extends all MMX instructions without affecting the mnemonic,
therefore these are just directed to the same function for now.
The UserspaceEmulator does not know this as of
this commit.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.

(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
