When doing multible codegen passes (such as building
compiler_rt and then something else) the TypeInfo cache code would point
to types from the prev code gen (such as the prev 'bool' type), giving
us errors like "expected type 'bool', but found type 'bool'"
This disabling of caching might have a performance hit, but correctness is better than
speed, so let's have this for now, until someone optimizes this
correctly (probably in stage2)
* bitreverse - give bswap behavior
* bitreverse, comptime_ints, negative values still not working?
* bitreverse working for negative comptime ints
* Finished bitreverse test cases
* Undo exporting a bigint function. @bitreverse test name includes ampersand
* added docs entry for @bitreverse
Prevents LLVM from generating debug info for
struct member functions with a pointer as the
first parameter as though the first parameter
were the implicit "this" pointer from C++.
* add `@bswap` builtin function. See #767
* comptime evaluation facilities are improved to be able to
handle a `@ptrCast` with a backing array.
* `@truncate` allows "truncating" a u0 value to any integer
type, and the result is always comptime known to be `0`.
* when specifying pointer alignment in a type expression,
the alignment value of pointers which do not have addresses
at runtime is ignored, and always has the default/ABI alignment
* threw in a fix to freebsd/x86_64.zig to update syntax from
language changes
* some improvements are pending #863closes#638closes#1733

it has a patch that adds an OS type, breaking the public API
this commit avoids depending on the last os type enum item,
but retains the safety assertion checks.
closes#1788
* codegen: LLVMConstInlineAsm is deprecated.
* codegen: replace commas in asm constraint strings by pipes as required by LLVM.
* ir: enforce usage of '=' constraint modifier for inline assembly outputs.
Others are not currently supported and this was just asserted alter in `ir_render_asm`.
* asm: forbid comptime_int/floats as inputs in favor of explicitely sized constants.
Fixes a crash due to comptime_int/floats having no type_ref.
* asm: handle inputs with integers of <8 or non power of 2 bitsize.
We widen them to the next highest power of two.
