[libc] Add more robust compile time architecture detection

2021-11-02T11:00:33+00:00

We may want to restrict the detected platforms to only `x86_64` and `aarch64`.
There are still custom detection in api.td but I don't think we can handle these:
 - config/linux/api.td:205
 - config/linux/api.td:199

[libc][nfc] move ctype_utils and FPUtils to __support

2021-08-06T17:29:41+00:00

Some ctype functions are called from other libc functions (e.g. isspace
is used in atoi). By moving ctype_utils.h to __support it becomes easier
to include just the implementations of these functions. For these
reasons the implementation for isspace was moved into
ctype_utils as well.

FPUtils was moved to simplify the build order, and to clarify which
files are a part of the actual libc.

Many files were modified to accomodate these changes, mostly changing
the #include paths.

[libc] Move FPExceptMatcher out of TestHelpers.h

2021-07-30T23:44:29+00:00

TestHelpers.h pulls few pieces from LLVM libc's unittest framework
which aren't available on platforms like Fuchsia which use their own
unittest framework. So, by moving FPExceptMatcher to a different file
we can exclude LLVM libc specific pieces in a cleaner way.

In a later pass, it might make more sense to rename TestHelpers.h also
to FPMatcher.h. That way, we can make macros like EXPECT_FP_EQ to be
equivalent to EXPECT_EQ on platforms like Fuchsia.

[libc] Fix x86_64 fenv implementation for windows

2021-07-27T20:53:01+00:00

All fenv functions are also enabled for windows. Since two tests,
enabled_exceptions_test and feholdexcept_test are still failing on
windows, they have been disabled.
