27af716c3a MSL: Emit F{Min,Max,Clamp} as fast:: and N{Min,Max,Clamp} as precise::. 
This roughly matches their semantics in SPIR-V and MSL. For `FMin`,
`FMax`, and `FClamp`, and the Metal functions `fast::min()`,
`fast::max()`, and `fast::clamp()`, the result is undefined if any
operand is NaN. For the 'N' operations and their corresponding MSL
`precise::` functions, the result is consistent with IEEE 754 (first
non-NaN wins; result is NaN if all operands are NaN).

We can only do this with 32-bit floats, though, because Metal only
provides these variants for `float`. `half` only has one variant of
these functions that is presumably consistent with IEEE 754. I guess
that's OK; the SPIR-V spec only says that `F{Min,Max,Clamp}` are
undefined for NaNs. Performance might suffer, though.

d3233690cb MSL: Support unordered relational operators. 
The SPIR-V spec says that these check if the operands either are
unordered or satisfy the given condition. So that's just what we'll do,
using Metal's `isunordered()` stdlib function. Apple's optimizers ought
to be able to collapse that to a single unordered compare.

348aecc59f Remove extra newline. 
vim doesn't display the newline terminating a file, because every file
is supposed to have one. Travis does. That threw me off.

87de951105 MSL: Fix naming issue of aliased global variables. 
When the name of an alias global variable collides with a global
declaration, MSL would emit inconsistent names, sometimes with the
naming fix, sometimes without, because names were being tracked in two
separate meta blocks. Fix this by always redirecting parameter naming to
the original base variable as necessary.

361fe52c9d MSL: Properly support passing parameters by value. 
MSL would force thread const& which would not work if the input argument
came from a different storage class.

Emit proper non-reference arguments for such values.
