change use to usingnamespace 
See #2014

`use` syntax is still accepted for now. `zig fmt` automatically
updates code. After a release cycle the old syntax will be removed.

remove octal and hex floats from the language

This is technically a breaking change but I would be
surprised if anyone was actually using this feature.

ad8381e0d2 Move tokenizer error location to offending char 
Previously, it pointed to the start of the current token, but this made
it difficult to tell where the error occurred when it was, say, in the
middle of a string.

simpler implementation of && and || hints 
This accomplishes the same goal, but with less changes, so that
I can backport copy elision stuff easier.

ALPHA_EXCEPT_C and case 'c', which is ALPHA's definition.

f06bce5dda introduce [*] for unknown length pointers 
See #770

Currently it does not have any different behavior than `*`
but it is now recommended to use `[*]` for unknown length
pointers to be future-proof.

Instead of [ * ] being separate tokens as the proposal
suggested, this commit implements `[*]` as a single token.

c5c9d98065 introduce align keyword 
* remove `@setGlobalAlign`
 * add align keyword for setting alignment on functions and
   variables.
 * loads and stores use alignment from pointer
 * memcpy, memset use alignment from pointer
 * add syntax for pointer alignment
 * slices can have volatile
 * add u2, i2 primitives
 * ignore preferred align and use abi align everywhere
 * back to only having alignOf builtin.
   preferredAlignOf is too tricky to be useful.

09bd4a9a86 compile-time f32, f64 operations are now correctly lossy 
previously we used the bigfloat abstraction to do all
compile-time float math. but runtime code and comptime code
are supposed to get the same result. so now if you add a
f32 to a f32 at compile time it does it with f32 math
instead of the bigfloat. float literals still get the
bigfloat math.

35d3444e27 more intuitive left shift and right shift operators 
Before:
 * << is left shift, not allowed to shift 1 bits out
 * <<% is left shift, allowed to shift 1 bits out
 * >> is right shift, allowed to shift 1 bits out

After:
 * << is left shift, allowed to shift 1 bits out
 * >> is right shift, allowed to shift 1 bits out
 * @shlExact is left shift, not allowed to shift 1 bits out
 * @shrExact is right shift, not allowed to shift 1 bits out

Closes #413
