This reverts commit 3370d58956ecc744a004dff47b0437473f0ef7da.
This commit was done with an LLVM build that did not have assertions
enabled. There are LLVM assertions being triggered due to this commit.

There are still a few occurrences of "stage1" in the standard library
and self-hosted compiler source, however, these instances need a bit
more careful inspection to ensure no breakage.
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
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.
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.
