      Normalize casing of hexadecimal digits · 822be9b2
      Mathias Bynens authored 
      This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.

Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters

Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

      [wasm] improve handling of malformed inputs · fd2bf837
      ddchen authored 
      When reading malformed input, the length of variable-length types can be very large. Computing operand length with this and adding it to PC will overflow and screw up decode.

This patch switches to unsigned int for arity and lengths, terminates loop analysis on error, adds overflow checking to BranchTableOperand, and adds a unit test.

      [wasm] Binary 11: br_table takes a value.
[wasm] Binary 11: Add implicit blocks to if arms.
[wasm] Binary 11: Add arities to call, return, and breaks
[wasm] Binary 11: Add experimental version.

This CL changes the encoder, decoder, and tests to use a postorder
encoding of the AST, which is more efficient in decode time and
space.

      [wasm] Rework encoding of local declarations. · 835c5e6b
      titzer authored 
      Local declarations were previously encoded as an optional set of
4 uint16 values as part of the function declaration. This CL
implements the current design of moving these declarations to
a list of pairs of (type, count) that is part of the body.

      [wasm] Add loop assignment analysis. · 0ab1e562
      titzer authored 
      This CL implements loop assignment analysis, a pass over a loop's body
to record local variables that are assigned. This pre-pass is similar
to that done on the JavaScript AST for the same reason: avoid introducing
too many phis at loop headers when building a graph.
