std.simd: change T to u16
The `element_bit_size` would break if `T` was signed due to `ceilPowerOfTwo` only working on unsigned numbers.

d1d892c83c SIMD size suggestions: suggestions code now compiles, added more
architectures
The idea behind this is using the register capabilities in safe amounts,
 there is still some consideration to be done.
+ Fixed compile error using std.Target.<arch>.featureSetHas
+ X86 MMX and "3DNOW" 64 bits register usage considered for vector size
+ Added ARM Neon recommened usage of 128 bits (The size of the register)
+ Added AARCH64 Neon and SVE for 128 bits. SVE could use in theory up to
  2048 bits, but found only evidence of functional 512 bits on a super
       computer, decided on using 128 bits as a safety
+ Added Altivec recommendation of using the 128 bits long register
+ Using MIPS msa 2x64bits capabilities, usage of 64 bits registers for MDMX
  systems, need testing on how using bigger values affect performance
+ Using V extension on RISC-V, which is extendable via instructions, decided on 128 bits
  as a value to not use all registers
+ in SPARC the 64 bits registers are used, a max of 32 registers
  are to be used for configurable simd instructions, decided on using
the size of the register, need testing on performance hit on using a
bigger sized register vector size

zig fmt: remove trailing whitespace on doc comments
Fixes #11353

The renderer treats comments and doc comments differently since doc
comments are parsed into the Ast. This commit adds a check after getting
the text for the doc comment and trims whitespace at the end before
rendering.

The `a = 0,` in the test is here to avoid a ParseError while parsing the
test.

std: SIMD utility functions
This file contains a collections of functions that may be useful for SIMD, such as generating a vector with a linear range of numbers starting at zero, joining two vectors together, getting the index of the first true in a vector of bools, etc.
