Support is added for parsing type parameters only if the ParseTypeParams
mode is set, otherwise emitting syntax errors for source code that is
invalid without type parameters.
Rather than have large conditional blocks switching between legacy
parser logic and new parser logic, effort is made to minimize special
handling for ParseTypeParams.

go/constant relies on strconv for parsing Go literals, while older
versions of strconv either lack recent Go language features (e.g., Go
1.13's new numeric literals) or have errors (e.g., mishandling of
carriage returns in raw string literals prior to Go 1.8).
This requires two changes:
1. Splitting out the internal/bytealg dependency into a separate file,
which can be easily substituted with a simple loop for bootstrap
builds.
2. Updating eisel_lemire.go to not utilize Go 1.13 functionality
(underscores in numeric literals and signed shift counts).

The current implementation copies Debug, clears a bunch of flags
that are meant to be considered OK, and then checks the result
against the zero value. But more flags are cleared than remain:
it's easier to write and to understand to just check the ones that
need checking.
This phrasing also makes it safe to move more flags into the struct.
It turns out that some of the flags being checked should probably
not be checked, but this CL is meant to be a strict semantic no-op,
so left a TODO to clean up the function a bit more later.

A common operation throughout the front end is getting the ONAME for a
method used in a method selector, method expression, or method value.
This CL adds MethodName as a uniform API for doing this for all of
these kinds of nodes.
For method selectors (ODOTMETH) and method expressions (ONAMEs where
isMethodExpression reports true), we take advantage of the Node.Opt
field to save the types.Field. This is the approach we already started
taking in golang.org/cl/271217 (caching types.Field in Node.Opt for
ODOT).
For method values (OCALLPART), we continue using the existing
callpartMethod helper function. Escape analysis already uses Node.Opt
for tracking the method value's closure's data flow.
A subsequent, automated refactoring CL will make more use of this
method. For now, we just address a few cases in inl.go that aren't
easily automated.

With this change, constant literals (and results of constant
operations) that internally become infinities are represented
externally (to go/constant) as "unknown" values.
The language has no provisions to deal with infinite constants,
and producing unknown values allows the typechecker to report
errors and avoid invalid operations (such as multiplication of
zero with infinity).
Fixes#20583.
