7c3896e6cd translate-c: Prevent mistranslation of fp literals 
When trying to retrieve 80bit fp values from clang using
getValueAsApproximateDouble we'd eventually hit the ceiling value and
return infinity, an invalid value for a fp literal.

Add some logic to prevent this error and warn the user.

Closes #8602

6cd71931cb stage1: Unbreak build on FreeBSD 
It turns out that the endianness-detection header delivered with the
softfloat library is extremely brittle and gives wrong results when
targeting FreeBSD (long story short, _BIG_ENDIAN is always defined there
and that breaks the #if defined() chain).

Use our own endianness detection header to work around any potential
problem.

std/crypto: use finer-grained error sets in function signatures (#8558) 
std/crypto: use finer-grained error sets in function signatures

Returning the `crypto.Error` error set for all crypto operations
was very convenient to ensure that errors were used consistently,
and to avoid having multiple error names for the same thing.

The flipside is that callers were forced to always handle all
possible errors, even those that could never be returned by a
function.

This PR makes all functions return union sets of the actual errors
they can return.

The error sets themselves are all limited to a single error.

Larger sets are useful for platform-specific APIs, but we don't have
any of these in `std/crypto`, and I couldn't find any meaningful way
to build larger sets.

e2cc02717e Fix .gitattributes rules that should be recursive 
These are currently incorrect according to the gitattributes(5) and

as we intended due to a bug until recently when that bug was fixed.
