Unsuffixed literals like 1 and 1.1, and free type parameters sometimes
have to be printed in error messages, which ended up with <V0>, <VI0>
and <VF0>. This change puts the words "generic" and "integer"/"float"
into the message so it's not a completely black box.
The gamma and bessel functions are of little utility outside a small specialized subset of use cases, and so they don't really make sense for inclusion in the standard library. The only reason they were included in the first place was to mirror libm, which is not a very good justification. If people need them for their own projects then they can make their own bindings to libm (which isn't too hard).

This is unnecessary and also leads to a bug: When the user specifies
```
#[crate_type = "rlib"];
```
rustpkg still creates a dylib.
Also it's good not to duplicate functionality. `build_session_options` handles this just fine.
Use a lookup table, SHIFT_MASK_TABLE, that for every possible four
bit prefix holds the number of times the value should be right shifted and what
the right shifted value should be masked with. This way we can get rid of the
branches which in my testing gives approximately a 2x speedup.
Dead code pass now explicitly checks for `#[allow(dead_code)]` and
`#[lang=".."]` attributes on items and marks them as live if they have
those attributes. The former is done so that if we want to suppress
warnings for a group of dead functions, we only have to annotate the
"root" of the call chain.
Close#11380 and #11440.

Since reader::vuint_at() returns a result of type reader::Res it makes sense
to make it public.
Due to rust's current behavior of externally referenced private structures,
https://github.com/mozilla/rust/issues/10573, you could still use the result and
assign it to a variable if you let the compiler do the type assignment,
but you could not explicitly annotate a variable to hold a reader::Res.
a30d61b05a removed all of the trailing whitespace in doc/index.md.
Unfortunately, that trailing whitespace was actually markdown syntax for
line breaks.
This fixes the incorrect lexing of things like:
~~~rust
let b = 0o2f32;
let d = 0o4e6;
let f = 0o6e6f32;
~~~
and brings the float literal lexer in line with the description of the float literals in the manual.
Specifically, dissallow setting the number base for every type of float
literal, not only those that contain the decimal point. This is in line with
the description in the manual.
In general, you can run "rustpkg help <cmd>" to see some specific usage information for <cmd>. However, this was handled in a very ad-hoc and buggy manner. For example, running "rustpkg help prefer" would actually show you the usage information for the "uninstall" cmd. Or "rustpkg help test" would show you the usage information for the "build" command. Or "rustpkg help list" would just run the "list" command (and not show you anything usage information)
This commit attempts to fix this by making a new HelpCmd (and handling it explicitly)
This fixes#11336
I guess the type sizes are correct for both OS X and iOS, but i am not certain.
In any case, i'd rather have any iOS build at all, so that we have something to improve upon.
